Math Activities
Math 1: Play with Pulleys
Run a piece of sting about 1 foot (30 cm) long through the hole in the spool and tie the ends of the string together. Slide the spool and the string onto the broom handle. Rest the handle across the two chairs with the spool hanging between.
 Put one pail on the floor and tie the end of the piece of ribbon to its handle.
 Slide the other end of the ribbon over the spool and tie it to the handle of the other pail, which should dangle in the air.
 Add a few pennies to the hanging pail. What happens to the pail on the ground?
 Return the pail to the ground and add a handful of pennies or marbles. Pull the handle of the hanging pail toward the ground. What happens to the pail filled with weights?
Discuss: Where can you see a pulley in the school ground? Why is the pulley at the top of the flagpole? What other toys can we make with a pulley?
What Happened?
As you added pennies to the hanging pail, it started to lift up the pail on the ground. A single fixed pulley lets you pull in one direction to move a thing in the other direction. This is handy: it means you don’t have to climb up a flagpole to raise the flag. Instead, you can stand safely on the ground and pull on the rope as the flag rises to the top!
Quiz: Draw a cycle which runs on pulleys.
Math 2: Wheels and Axles
 Have your child place the two chairs backtoback, with about 1′ of space between them.
 Ask him to rest the handle of the broom across the two level slats.
 Tie a 1′ piece of string to the handle of the bucket.
 Have him tape the free end of the string to the center of the broom stick.
 Pour some pennies or marbles into the bucket to slightly increase the weight.
 Ask him to turn the broom handle with his hand to begin raising the bucket high into the air, then turn the handle the other way to lower the bucket.
 Tape the ruler parallel on top of the broom, near the broom handle. The ruler should overlap so it’s slightly beyond the broom handle.
 Now, have him turn the broom handle again using the ruler to lift the pail. What was different?
 Ask him if the ruler made it easier, or more difficult to lift the pail. The ruler, which symbolizes the “wheel,” helps to turn the handle, or “axle,” with less exertion.
Discuss: What happens to the effort when we add the pennies to the bucket? Why is it easier to lower the bucket than to raise the bucket? Why did it become easier to lift the pail with the ruler attached to the axle?
Explain to him that his hand would have to move farther using the ruler, but he exerted less force to make the bucket lift. This shows that the larger the wheel, the easier it is to lift a heavy load, which helps conserve energy and makes work go faster.
Quiz: In a village, where is a pulley and rope used?
Math 3: Understanding Volume
 Have your child fill the bowl halfway with water and mark the water level with the marker.
 Ask her to make a fist and put it in the bowl of water. Mark the new water level to indicate how much the water has risen. The space between the first and second mark represents the volume of your child’s hand.
 Have all the members of the family put their fists in the bowl of water, marking the water each time. Whoever displaces the most water has the biggest fist!
Discuss: What is the relation between height of student and fist volume? Does closing the fist
or leaving it open, change the volume? Do objects of equal volume have equal weight?
Quiz: How can you use this method to find out which of the two irregular shaped stones is heavier?
Math 4: Play the Shape Twister Game
 Set the stage. Explain that this is a fun game using colors and shapes, while following a set of directions that can be a little tricky. Let your child know you consider this a challenge—but one that she can also do well.
 Make the game. Have your child use crayons or markers to draw 2 of each of the following shapes: square, rectangle, triangle, diamond, circle, & star. Make them fairly large—at least 68” across, and use plenty of different colors of paper. Then lay them in rows on the floor.
 Make directions. Ask your child to create a list of directions. Either you or he can write them on a sheet of lined paper. Examples: “Place your right hand on the ____ .” “Place your left hand on the _____ .” “Place your right foot on the ______ .” “Place your left foot on the ______ .” “Move your right hand and place it on the _____ .”
 Make a spinner. Help your child use crayons and construction paper to create a paper spinner showing each of the colored shapes they have created. Draw a circle on white paper, and divide it into sections using a pencil. Have your child color each section with one color crayon. Have your child draw a picture on each colored section to match the shapes they created. Then cut out an arrow from another piece of construction paper, cut it to fit the spinner circle, and fasten it at the center with the paper fastener.
 Play! Help your child play the game by reading a direction from their list. Then spin the spinner to determine which colored shape they will land on. Continue until they have identified all of the colors and shapes. This is a great game to play with older siblings as well. After all, you’re never too old to have fun…and learn math while you’re doing it.
Discuss: Which shape do you see the most around you? What shapes are our rooms? Why?
Quiz: What is your favourite color? Why is it your favourite?
Math 5:Group It! A Skip Counting Activity
 Have your child gather as many pairs of shoes from the household as he can. Ask him to line them up in pairs on the floor. With your child, count by 2s to find the total number of shoes. Then count each shoe again, counting by 1s. Ask your child if it’s quicker and easier to count by 2s or to count by 1s. Finish by counting again by 2s—the more practice the better. Roll out some paper and trace the shoes in pairs. Let your child color the pairs.
 Pour some paint in a sturdy paper or plastic plate. If it’s too thick, don’t hesitate to add some water to dilute it. Have your child put her hands, palms down, in the paint and make handprints on a sheet of paper. Ask her to press down all four of her fingers and her thumb. In this part of the activity, your child is making groups of five. Have her make as many handprints as she wants (at least 10). Count by 5s to find the total number of fingers and thumbs shown.
 Place a group of pennies on the table. Ask your child if it’s faster to count the pennies by 1s, 2s, 5s, or 10s. Have him place the pennies in stacks of 10. Help him count the pennies by 10s to find the total number. Simple? Yes. But a great introduction to skip counting, an important first grade skill. So keep the paint and pennies handy. And look for everyday excuses to count in groups!
Discuss: Examples of objects that you see in groups in real life? Which of the group sizes makes life easiest for us? Why?
Quiz: 10 groups of 2 Rupee coins will equal to how many Rupees?
Math 6: Play the Number Line Game!
 Shuffle the number cards and place them face down in a stack. Have your child pick up the first card.
 After she’s looked at the card, ask her to name the number that comes before it. Then have her name the number that comes after it. If your child hesitates, you can rephrase the question by asking which number is 1 less (or 1 more) than the card she is holding.
 Using the number line, have your child check to see if she has named the numbers correctly. If so, she keeps the card. She can start a “winnings” pile to keep all of the cards she’s won.
 Continue in the same manner until your child has looked at all of the cards. Ask her to count the cards in her “winnings” pile.
All done? Record the number of cards your child has won so that the next time you play the Number Line game she can try to beat her score!
Discuss: What was the biggest card you picked up? The smallest? Where will 0 come on the number line?
Quiz: Draw a histogram of winnings.
Math 7: Weight Wonders: Big and Light…Heavy and Small?
 Set it up. Start by telling your child that you will be doing some science together. You’ll begin by looking at some regular things and making guesses (hypotheses) about which one is heavier. Check your young scientist’s knowledge: how will we know which items are heavier than others? (Expect the answer, “I’ll hold them,” and don’t be surprised if your kid adds, “Duh.”) Do continue, however: remind your child that to be absolutely accurate, he’ll also need to weigh the items. Depending on your scale, you may even want to introduce the concept of weighing in either pounds and ounces, or in grams. Now help your child make an “observation” chart on his lined paper. Write “Heavy or Light” on the top, and then fold the paper in half lengthwise. He’ll use the chart to write the names of objects, or a picture of them if he prefers, and to record which is heavy or light.
 Gather the items. Assemble all of the chosen objects on a table or countertop. Ask your child to name or point to two objects. Move those objects so they are next to each other and separate from the other objects. It’s important for you to do this step, as your child will get a chance to handle the objects later in the activity.
 Make predictions. Ask your child just to look at both objects she selected. Look at their height, length, shape, and any other distinctive features. Ask her to tell you, just from looking at them, which object she thinks is heavier.
 Evaluate. Once your child has guessed, ask her to pick up the objects. Ideally one in each hand works the best, but if an object is too heavy, it may be picked up individually. Ask your child if she wants to change her guess or keep it the same.
 Weigh in. Using a kitchen or bathroom scale (whichever is more appropriate) weigh the two objects. Was your child right? If not, can she figure out why their guess was wrong? Talk about how the scale measures the mass (weight) of an object, but some things may have lots of volume (size) with very little mass. Write the weight of each object below its name or picture on the observation chart.
 Repeat. Place those objects aside and ask your child to pick two more to compare.
Repeat these steps as long as your child is interested in the activity…and don’t hesitate to pull it out as you explore new things, whether it’s seashells from the beach or pinecones from the forest. The world is crammed with exciting reminders that when it comes to volume and mass, what you see is not always what you get…and that’s a very cool thing indeed.
Discuss: How does a weighing scale work? Can we find out which is the heaviest of all the objects we weighed? The lightest?
Quiz: Why are some big objects light and some small objects heavy?
Math 8: Make a Clock!
 Start by making a small hole in the centre (With a plate, you can use scissors. With a frisbee, you’ll need to use a drill). Let your child know he’s going to make his very own clock and that the frisbee or paper plate will serve as the clock face. If you have an analog watch or clock somewhere in the house, bring it to the table to use as a model.
 Ask your child to place one sticker at the top of the “clock face” and one directly opposite, on the bottom. With the marker, have him write the number 12 on the top sticker and the number 6 on the bottom sticker. Now ask him to place one sticker on each side, halfway in between the top and bottom. He should write 3 on the righthand sticker, and 9 on the lefthand sticker. Then, referring your analog clock as a model, ask him to fill in the other numbers on the clock using the stickers and his marker.
 Now it’s time for the clock hands! Using the poster board, cut two arrows—a longer one for the minute hand, and a shorter one for the hour hand. Pierce the ends of the arrows with the paper fastener, slide it through the hole in the centre of your clock face, and secure it at the back.
 Pick a day of the week and, with your child’s help, create a list of his activities. This might include soccer practice, a violin lesson, going to school, a play date, a shopping trip with grandma…or just time spent eating a snack. Next to each entry, write the time the activity begins, rounding to the nearest half hour.
 Make it concrete! Help your child identify the hour hand and the minute hand on the clock face. Remind her that the hour hand shows the hour and the minute hand shows the minutes. Now, make sure she knows which hand of the clock is longer (the minute hand) and which hand of the clock is shorter (the hour hand). Pick an activity and find its time on the clock. Start with the activities that begin on the hour and then move to the activities that are on the half hour.
 If your child is having trouble, move the hands around the clock, naming each hour as you go. Then give your kid a go at it. Not quite there yet? Don’t worry. Telling time always becomes easier with practice…and time of course!
Discuss: How do you think a clock works? Show us the time you get up in the morning. The time you go to sleep. Who gets up the earliest? Who goes to sleep the earliest?
Quiz: From what time to what time do you watch TV at home? So how many hours in a week are you in front of the TV?
Math 9: Slap It!: An Odds and Evens Card Game
 The dealer shuffles the cards and then deals them out, face down, to each player in rotation, until all the cards have been passed out. (It doesn’t matter if one player gets an extra card or two!) Players arrange their cards, without looking at them, into a neat pile in front of them.
 The object of the game is to win as many cards as possible, by being the first to slap each odd number as it lands in the center.
 Beginning with the dealer, each player lifts the top card off of his pile and places it face up in the center, making sure to turn up the card so it’s facing away from him, so he doesn’t see it any sooner than anyone else.
 When the card put down is odd, the first player to slap his hand down on it takes it, as well as all the cards beneath it. The player winning these cards turns them face down, places them under his pile of cards, and shuffles his deck to form a new, larger pile. He then places the pile in front of him as before.
 If more than one player slaps a card, the one whose hand is directly on top of it wins the pile. If a player slaps at any card in the center that is not odd, he must give one card, face down, to the player of that card. When a player runs out of cards, he stays in the game until the next odd card is turned. He can slap at that card in an effort to get a new pile. If he fails to win that next pile, he is out of the game.
Play continues until one player has won all the cards. That player is the winner!
Discuss: All even numbers are in the table of 2. What table do all odd numbers come in? We have decided to change the rule of this game. What do you think should be the new rule?
Quiz: How many people should be in the group that plays this game? Why?
Math 10: Seventeen: A MathBuilder Card Game
 Prepare your materials. Start with your deck of cards. You will need all aces (each counts as “1’), and all numbered cards between 2 and 8. Make sure you pull out all nines, tens, jacks, queens, and kings. You can save them for more advanced games later.
 While this game can be played by up to four players, you’ll probably want to start with just two. Shuffle your number cards and put them face down on a table. Then have each player pull out five cards. Take turns putting cards down, one at a time, and counting the total made when you add the pile together.
 “Winning” and “Losing”: The goal is to get as close to 17 as possible. Let’s say, for example, that Player 1 puts down a “7” card, and then Player 2 puts down a “5” card. If Player 1 can add another “5,” she wins the round and gets a score of 17! That’s the clean way to win a round. But she can also win if she goes slightly over—say, to 19—but she must subtract the extra “2” from her score, so she only gets 15 points. The goal of the game (aside from complete Math Facts Mastery, of course!), is to have the largest number of points when the game is done.
Special note: Counting up the final scores usually means adding several digits. This may be a good stretch for some kids, but lots of first graders will find it hard. It’s helpful to have either a calculator, or a parent helper, or both ready.
Discuss: If we added card numbers 9 and 10, would the game become easier or difficult? Why?
Quiz: How can we change a rule of this game to make it different?
Math 11: Measuring Water
 Help your child fill the mixing bowl with water, all the way to the very top.
 Have her place the bowl in the tray.
 Then put one of your pieces of fruit into the water, so that it splashes over the edge and into the tray.
 Pour the water from the tray into the measuring cup. Have her read how many ounces of water is in the measuring cup and explain that the fruit took up space in the bowl and pushed out water to make room. Then explain that the weight of the water splashed out by the fruit is equal to the weight of the fruit. This game is a great way for little minds to expand and gain appreciation for science!
Discuss: Get two potatoes which almost look to be the same weight. Find out which potato weighs more, using this method.
Quiz: Choose the best shape for a measuring cup from shapes below. Why did you choose this shape?
Math 12: Going to the Park? Make a Map!
 First, pick a park that’s not too far from home. (First grade social studies curriculum typically emphasizes getting to know your neighborhood and town!) Then help your child make a simple “birds eye” picture of the area: start with your home, and then help your child draw the roads or paths that your child and your visitor will need to take to get to the park. At the end, be sure to mark the destination clearly, too.
 Help your child write each road’s name as needed for the map.
 Now, using either a separate sheet of paper or working on the side of the map, help your first grader write step by step directions as to how to get to the park. For example, you might say something like, “turn left at the corner of Briar Street onto Bramble Drive. Go straight,” and so on.
 You can do this activity several days before your guest arrives, so that you and your child can take your homemade map with you on a clipboard and see if you can get to the park together. And as you go, help your child estimate distances (if you bike or drive, you may even have an actual odometer) for each step of the instructions. Then have your child write these distances next to each step of the directions.
 Invite your child to color the route, and even make arrows along the map to show the way. When the masterpiece finished and ready, you can consider laminating the map, too.
When your outoftowner finally arrives, you and your child will have the perfect way to welcome them – and your first grader will have gained some invaluable realworld social studies practice, as well. In case there’s a shadow of a doubt about how important and relevant these skills are, invite her to check out a website like “Map Quest.” Finding out how to get to places is always exciting and it also gives your child a chance to try out a “grownup activity.” First grade is a great time to start!

Math 13: Wolfie Wolf! An Outdoor Math Game
 To set up the game, take out your 12 pieces of construction paper. On one side of each piece, write out the name of a number (one, two, three, and so on) in very large, clear block letters. On the back of each paper (held horizontally), write the number itself—again in very large, very clear block letters.
 Taking your numbers with you, stand at one end of an open space, and have the children stand at the far end—far enough to be a sprint away, but not so far that they can’t see your signs.
 From this point forward, you are the “Wolf”, and the children are your innocent “lambs”. Have them start the game by asking you, “Wolfie Wolf, what time is it?”
 Hold up a written number, and have the kids take that number of steps forward. When they’ve stopped, put down your sign and pretend to be inattentive or asleep. They’ll ask again, “Wolfie Wolf, what time is it?” and again you hold up a sign. If they get too close, show a card with the numeral side out—that means they must take that many steps back.
 Keep going for several more “steps,” forward and back, until your little lambies seem to be lulled. Then when they ask “what time is it?” give them a surprise. Shout, “Time for Dinner!” and take off chasing them! If you “catch” a child first, she can be “Wolfie” next time. If she gets to your home base first, she wins—and you’re still the Wolfie!
What’s Going On: For experienced readers and mathematicians, it’s easy to forget how many kinds of pathways kids need to use in order to understand words and numbers. Activities like “Wolfie” allow kids to put sight and sound together with “kinesthetic” learning—knowledge that comes through physical experience. It’s powerful learning . and powerful fun at the same time!

Math 14: Go, Seeds, Go
!
 Go on a seed scavenger hunt with your child. In your backyard, look high and low on trees, shrubs, in flowerbeds, on the ground, and elsewhere in the garden to find a variety of seeds. Good seeds to look for would be: dandelion seeds, milkweed seeds, maples, acorns, and burdock. And before you go inside, be sure to check your outerwear, especially your shoelaces, for hitchhiking seeds.
 Bring the collection into the house and spread the seeds out on a piece of newspaper to dry. Depending on the variety of seeds and the time of year, this may take anywhere from a few hours to a few days.
 When dry, examine the seeds carefully and think about how each seed gets to where it’s going. Some seeds such as acorns simply fall from trees. Others like as dandelions and milkweed seeds have fluffy material that work like parachutes to carry them on the wind. Maple seeds also have parts that look like wings; their leafy flaps flutter in the wind and give them lift so they can travel as they fall from the tree. Other seeds such as acorns and sunflower seeds are carried around by animals like squirrels, birds, and chipmunks. And still others have special parts that allow them to hitch a ride on our shoelaces and in the fur of animals. Burdock seeds, for example, have hooklike parts that stick to our clothing like Velcro when we brush against them. Be sure to examine the seeds closely and discuss with your child how each might get from place to place, based on the appearance and special parts of the seed.
 Finally, compile your findings in a book. Have your child make a page for each type of seed in her collection. At the top of the page, let her glue the seed to the paper. At the bottom of the page, have her write the name of her seed and its method of travel. For instance, she can write: “Dandelion seeds travel by floating on the wind.” If you’re not sure what kind of seed you’ve collected, let her describe the seed by how it travels.
 Finish writing down the findings, and now your child will have a colorful book of seeds to refer back to!
Discuss: Describe the number of ways a seed can travel.
Quiz: Why do plants produce seeds? When do seeds germinate? Math 15: Make Ladybug Tightrope Racers
 Start by cutting out two ladybug bodies in black (see our printable template), and two red ladybug bodies. Glue a red body onto each black piece, and then stick the dots on the wings to create a ladybug. Cut a pipe cleaner in half, and then, in turn, bend each piece in half and poke the ends up through the ladybug’s head to make antennae.
 Now cut a 3” section of straw, and glue it onto the bottom of the ladybug with strong craft glue.
 While the ladybug racing rig is drying, take out the two pieces of string. Attach each one to a table leg or a chair. Use a yardstick to measure 20 5” intervals (a total of 100 inches), and mark them clearly with a sharpie pen. Once the ladybug is dry, run the string through the straw and attach the other end to a chair or table to make a nice firm tightrope ride.
 Time to play! For most first graders, the first impulse will be to grab the bug and push. But now’s the time for your young scientist to practice a little physical science. Have him stand just behind the bug and blow, using air pressure to send it along the string. How far can the bug go in one breath? Two? Three? Kids can measure exact inches—and practice counting by fives—as they try to be the first to move the ladybug 100 inches down the line.
Discuss: Speed = Distance / Time
Quiz: Ladybugs can fly. Draw a ladybug in flight.
Math 16: Halloween Shadow Pumpkin Symmetry
 Fold the construction paper horizontally (“hamburger” style).
 Place it on table in front of your child so that it’s vertical (9” high, 6” wide) with the fold on the left—like a greeting card. Help her trace half of a pumpkin shape, starting at the fold, going out to the edges and using as much of the paper as possible.
 Have her draw one eye, half a nose (this will touch the fold), and half a mouth, with as many scary teeth as she likes.
 Now help her use the scissors to cut the pumpkin out of the paper and the face shapes out of the pumpkin. This is a good time to explain the concept of symmetry to your kindergartener and why the pumpkin face will be symmetrical when you are done.
 Open it up and you’ll have a symmetrical spooky face!
 Now help your kindergartener glue the pumpkin onto a sturdy sheet of cardboard. Your child can probably cut around the edge of the pumpkin herself, but you should plan to help cut out the eyes, nose, and mouth with an Xacto knife.
 Sandwich the whole spooky pumpkin between two layers of contact paper, or laminate it, and again trim the edges.
 Staple or glue a tongue depressor or popsicle stick onto the back of the pumpkin. If you have a yard with ground lights, you can stick the pumpkin in front of them and let the light shine through to make a Halloween shadow decoration; or play with it indoors by placing it near a light and letting the spooky shadow spread on a wall. You’ll have a great Halloween decoration along with a fun math and art lesson as well.
Discuss: What living things are non symmetrical? What are symmetrical?
Quiz: Finish this worksheet.
Math 17: Popsicle Stick TicTacToe
 Help your child glue popsicle sticks into a tictactoe board.
 After the sticks have dried, show your child how to wrap yarn around the four inside corners and then tie off with a knot. This helps the board keep its durability.
 Have your child select two colors of paints for the rocks. Paint six rocks one color and six rocks a different color. Allow them to dry.
 Once the game board and the game pieces are complete, go ahead and play! Each person takes a turn placing their rocks in the tictactoe grid, trying to be the first player to get three of their rocks in a row. In the event that neither player can make the pattern, then it is a draw and you play again.
To make a larger board, have your child help you hold and glue sticks together in a larger grid. You can vary the game by having each player attempt to get four in a row, on a 5×5 or 6×6 grid.
Discuss: Trace back the steps based on a half finished game.
Quiz: Who will win this game? Who do you think started the game?
Math 18: Play Pennies, Dimes, Dollar!
In first and second grade, kids spend a lot of time learning to count and use money. Don’t be surprised if it doesn’t quite “gel” for your child for several years. Our money system really doesn’t make much sense until kids are fully comfortable with quite a few fundamental math concepts, including the 1 to 100 number line and place value (tens, hundreds, and so forth). Here’s a coin counting game for first and second graders that helps move that process along.
 In this game, the winner will be the person who, in six turns, can put together dimes and pennies to total as close to $1.00 as possible.
 Start by making a scorecard for each player. Have her create a column labeled “pennies,” a column labeled “dimes,” and a “value” column.
 Have her place the dimes and pennies in two piles in the middle of the table, between players, so that everyone can reach them.
 Players should take turns rolling the die. Each player will take the exact number of either dimes or pennies as are shown on the die. For example, if the die shows the number “5,” each player might take 5 pennies, or one player might take 5 dimes and the other 5 pennies.
 Players put their dimes in the dime column and their pennies in the penny column, and write the value of the coins they picked up after each turn.
 As the rolls add up, so will the coins. Whenever a player gets ten pennies, she must automatically trade them for one dime, and place the dime in the correct column.
 After six turns, everyone stops and counts up the money. Who got closest to $1.00? That’s the winner!
This game allows kids to explore three primary math concepts in one: by moving pennies into the tens column, your child enacts the idea of “place value”—“ones,” “tens,” “hundreds,” and so on. By counting up to $1.00, your child practices moving around on the number line…with money. Not bad for a simple game; in fact, we recommend you play it over and over again with your young mathematicians and prepare to be delighted by not only the fun, but the learning, you share.
Discuss: Write down the note / coin denominations available. Is there a pattern you can see here?
Quiz: What is the maximum money that you could have collected in this game?
Math 19: Play Ice Cream Addition!
 Print enough copies of the Ice Cream Worksheet so that every player has one.
 Determine who goes first. The first player will roll the dice. On a blank sheet of paper, the player will then write the addition problem out using the numbers he rolled as the addends. If he rolled a 3 and 4, for instance, he would write the problem this way: 3 + 4 = 7.
 The first player will then color the sum on the ice cream cone. In the example 3 + 4 = 7, 7 is the sum and would be colored on the cone.
 The next player rolls the dice to determine his addends, writes the addition problem, and colors in his sum.
 Continue playing with each player taking turns. If someone rolls a sum that is already colored on his sheet, he loses that turn. Try to use the math vocabulary as you play this game and see how quickly you learn these new words.
 The first player to sum up all his problems and color in his entire ice cream cone wins the game! Celebrate by eating some real, delicious ice cream for a treat!
Discuss: What do you like more: an icecream in a cup or cone? Why?
Quiz: If we add up all the numbers on a dice, what is the answer?
Math 20: Addicted to Addition
 Ask your child and her friends to create the game board. Tape together 4 sheets of paper. Use the marker to draw a 2 x 2 grid on each piece of paper. You should now have a 4 x 4 grid to play on.
 Announce that aces = 1.
 Ask one of the players to take out and set aside all of the face cards. Then they can divide the cards they removed into red and black cards. Each player gets either the red or black suits of the separated cards.
 Players each take a turn setting any one of their cards into one of the spaces on the game board.
 Players who create a line of 4 cards in a row in any direction (including diagonally), that adds up to either 10 or 20, wins one point. An example of cards adding up to 10 would be if the cards in a row were 2 + 3 + 2 + 3 = 10.
 Continue playing until a player wins the game by earning 10 points.
Discuss: In how many ways can you win?
Quiz: In the play shown above what two cards, when placed in the first row, will make you win one point?
Math 21: Sum It Up
Try to use as many numbers as possible in your quest to victory! Draw from a deck of cards to determine your number, then mark all of the different numbers that can be used to create sums equal to the number you picked. Your child will need to engage his problem solving skills in order to participate in this addition game. Before you know it, he’ll be ready to tackle subtraction!
 Write the numbers 110 on the index cards.
 Lay the index cards on a flat surface, making sure they’re far enough apart from one another so that if there’s any counter spill over, it’s no big deal.
 Shuffle the playing cards and place them face down in a pile.
 For the purposes of this game, aces= 1.
 Players take turns drawing a card. Once a card is drawn, the player should place a counter on the number value of the card.
 Then, they must figure out which numbers can be used to create sums that equal the value of the card. (For example, if a player draws a 7, they could cover up “6”, “1” and “5”, “2” and “4”, and “3.”)
 Now for the catch! Each player has only 10 seconds to say their number and the sums equal to their number aloud and place their counters on the index cards.
 Once there are no more cards left, players should tabulate how many counters they used. The player who’s used the most counters wins.
Once your kid has mastered addition, have him try out some subtraction. Play this game again, but instead of finding numbers for sums, he should mark the numbers that can be used to create differences.
Discuss: Which number can give you the maximum number of counters? Which gives you the minimum?
Quiz: How many counters can get used for 20?
Math 22: Roll the Dice
Practice adding in a whole new way! You’ll need five dice, paper and a pencil in order to get started. Shake those dice and try to roll big numbers. Then add them up and cross your fingers. If your sum is larger than the other players’ sums, you win!
Guide your child through the process at first, and gradually let him take ownership of the game. You’ll see his confidence with addition improve in no time!
 Decide who will go first. The first player should roll all 6 dice. Each player should add up the total from their roll and record it.
 The player with the highest sum from round 1 earns 3 points. The player with the second highest sum earns 2 points. The rest of the players receive 1 point.
 Play continues for 10 rounds, or decide on a time limit.
 After the game is finished, have the players add up their scores.
 The player with the highest sum wins.
Discuss: Draw a histogram of sums got in different turns. Is there a pattern?
Quiz: Each of the 5 dice has a different number. What can be the sum?
Math 23: Elevens Card Game
 Ask your child to shuffle the deck of cards. Let her know that for the purposes of the game aces = 1.
 Have her deal 9 cards face up in a 3 x 3 square. The remaining deck should be face down on the table.
 Have her cover face cards that she dealt by placing fresh cards from the deck face up right on top of them.
 Ask her to look for any combinations of cards that add up to 11. When she recognizes a combination, have her remove those two cards from the deck and replace them with new cards.
 Continue until all cards are used. If there aren’t any cards that create 11, take all 9 cards and shuffle them back into the deck. Then, lay out a new group of 9 cards.
Discuss: Try the same game creating sums of 10 or 12. Try assigning numbers to the face cards and include them in later rounds.
Quiz: What is the maximum sum in the game shown above?
Math 24: Don’t Get Mad, Get Even
 Lay out all of the cards face up, in a horizontal line. For this game, aces= 1.
 Let your child know that he has one minute to pick out and remove the pairs of cards with even sums (for example, 2 + 6 = 8).
 Count and record how many cards remain. One card= 1 point.
 Tell your child that the fewer points he accumulates, the better.
 Shuffle the cards again and lay them out in a line. In this round, encourage your kid to try to remove more cards than he did the last time!
 In the final round, give your kid an unlimited amount of time to try to pair up and remove all of the cards. If he’s successful, tell him he gets to subtract 10 points from his score.
Helpful tip: If you’re playing with more than one player, you might want to use multiple decks of cards.
Discuss: How can we modify this game for subtraction and multiplication?
Quiz: A player is given 4 cards and is able to remove only two. What conclusion can you draw?
Math 25: Homemade Stamps
 Help your child collect the materials for this activity. Stamp bases can be made from wood blocks of various sizes, empty plastic or wood sewing thread spools, and/or wine corks.
 The shapes that will be glued onto the bases can be made from buttons of various shapes, sizes and textures, and also from foam craft pieces. Some foam shapes have sticker backings, but foam shapes that are not stickers can also be used.
 Your turn: use a glue gun to attach one button to the end of a stamp base. Repeat for other buttons that she thinks will make good stamps, using a separate stamp base for each button.
 If your foam shapes have sticker backings, it is very easy for your child to peel off the sticker backing and attach a shape to one stamp base. If the foam shape is not a sticker, use the hot glue gun to attach a foam shape onto a stamp base. With foam initial letters, she can create stamps for her own initials. It is okay for the foam shape (or button from step #3) to be bigger than the stamp base; just use glue under the part of the shape or button that will attach to the stamp base.
 After the glue has dried on the newlycreated stamps, let your child play around with them and test them out! Give her ink stamp pads in various colors and paper. Let her dip the stamps in ink and stamp away!
 She may want to give stamps to her friends as gifts to share the fun!
 Need ink to go along with your new stamps? Try this recipe.
Discuss: Where have you seen such stamps being used? What purpose do such stamps serve?
Quiz: Shown is a stamp. What will you get after stamping it on paper?
Math 26: Play Egg Carton Addition
 Use your marker to put a number in the bottom of each egg cup in the carton. (If you have a math beginner, start by cutting your carton in half, so you only have six cups; if you’ve got a kid who’s surging ahead, go ahead and use all twelve!)
 Put a bowl of game tokens (pennies, marbles or beans) in the center of your table or play area and place two pieces into the egg carton.
 Each player takes turns shaking the carton and then writing an addition problem on their paper using the two number sections the pieces landed in. Let’s say, for example, that the two pieces landed in 4 and 6. The addition problem would then be 4+6.
 The person with the highest sum after each player has had a turn would then take a token from the bowl in the center of the table. If a wrong answer is given, a token is returned to the bowl. In case of a tie, each child takes a token.
 Continue playing until each player has collected five tokens. Do this a few times, and be prepared to see steady gains in your young mathematician’s adding confidence!
Discuss: Make a record of additions. Which answer came most often?
Quiz: A game was played with a carton egg. If the person who got the winning token got 10, then what numbers did the two pieces land up on?

Use a weighing balance to illustrate the concept of less, more and equal. On second thoughts, can we get students to make a simple weighing balance. (This can be a class 4 activity)
Role play. One person takes on the role of a shopkeeper and the remaining students have to buy from his shop. We can use real or fake money. One variation is that teachers dress up as helpers – and offer their services. The prices are listed out – and then students negotiate and do transactions with teachers. Would be interesting to see how students allocate money if they are given a sum at the start 🙂 We discussed buying a second hand weighing balance. Also a digital weighing scale for students to measure their weights – or heavy objects.

Math 62: Digit Count
Jyoti was teaching 91 to 100. Students were busy writing and then having fun by underlining the written numbers with different crayons. Good chaos with mini fights when a student refused to let go his crayon. Challenged students to tell me how many times did 9 get used in the page. After most students could get that, the next challenge was if we were to write 1100, then how many times would 1 get used. This required more time. In case of any answer mismatches, asked groups to check the written work of each other, rather than come to me. Eventually, most people got this one right also. (they had to write down all the numbers, some did it in ascending order, others randomly).
Discuss: How many 2/3/4 digit numbers exist?
