Math Activity Calendar: July

  • July 1: National Blueberry Month

    Ask your child to estimate the number of berries in a container of blueberries, and then count them to find out. Was your child's estimate more or less than the actual count?

  • July 2: Blueberry Fan Survey

    How many blueberry fans do you know? Divide a sheet of paper into two columns. Write "yes" at the top of one column and "no" at the top of the other. Now ask friends and family members if they like blueberries, putting checks in the appropriate columns. Were there more yes's or no's? How many more or less?

  • July 3: Count on 10

    Today is July 3. What date will it be in 10 days? In 20 days? How far can your child count by 10's, starting with the number 3?

  • July 4: Independence Day

    Frost a batch of cupcakes with white frosting. Then decorate them with patterns made out of small blue and red edibles (e.g., blueberries, raspberries, strawberries, M&Ms, etc.). For example, alternate blueberries and raspberries or alternate a row of blueberries with a ribbon of red licorice.

  • July 5: High Five!

    Make handprints with Curious George, and see how far your child can count by fives in this online game.

  • July 6: Small to Large

  • July 7: Chocolate Math

    Today is a good day to eat chocolate, and have fun with math at the same time! There's lots of math in a package of M&M's. Sort the M&M's by color. Make color patterns (e.g., red — yellow — red — yellow; or red — red — yellow — red — red — yellow ). Add groups of M&M's (e.g. 3 yellow + 4 red equals 7).

  • July 8: Jars and Lids

    Get eight jars or storage containers with lids. Remove the lids and put them to the side. Challenge your child to find the correct lid for each container.

  • July 9: How Many Will Fit?

    Get a small container and some unshelled peanuts, grapes, or other small edible. Ask your child to estimate how many will fit into the container. Have him check his estimate by counting the objects as he drops them in one-by-one. For younger kids, use a container that holds no more than 10 items.

  • July 10: Making 10

    Put 10 pennies (or other small items). Ask your child to divide them into two groups that add up to 10 (e.g., one group of 8 pennies and one group of 2 pennies; or one group of 5 pennies and another group of 5 pennies). How many different ways can she come up with to make 10?

  • July 11: Feel the Heat!

    July can get very hot. Keep track of the temperature for the next week. What was the highest temperature? What was the lowest? Pick a specific temperature (e.g., 80 degrees), and at the end of the week count how many days were above that temperature.

  • July 12: Shape Match-Up

    Trace the outlines of several small objects (e.g., key, coin, block, crayon) on a piece of paper. Ask your child to match the objects to their outlines.

  • July 13: Color Match-up

    Divide a paper plate into 8 equal wedges. Use crayons or markers to color the wedges different colors. Cut 8 circles out of paper and color them the same colors as the wedges. Ask your child to match the circle colors to the colors on the paper plate.

  • July 14: Measuring 'Round and 'Round

    Use a piece of string to measure the circumference of a round object such as an orange. Cut the string to the exact length. Do the same with several other objects (e.g., a ball, apple, lime). Label each piece of string. Ask your child to put the pieces of string in order from shortest to longest.

  • July 15: More Measuring Fun

    Measure the distance around the heads of all your family members using a piece of string. Cut a length of string for each head, and label them. Ask your child to compare the lengths, and tell you who has the biggest head and who has the smallest head.

  • July 16: Flower Compare

    Flowers come in all different sizes, shapes, and colors. Some smell and some don't. Go on a flower hunt with your child, and find four or five different kinds of flowers. Ask your child to look at the flowers and tell you how they are alike and how they are different.

  • July 17: Yellow Pig Day

    Did you know that you can draw a pig out of circles? Here's how: draw a big circle for the body, a smaller circle for the head with even smaller circle inside for the nose and eyes. Add four more circles for the arms and legs, and two for the ears. Add a squiggly tale, and color it yellow. How many circles did you draw?

  • July 18: Circle Hunt

    Go on a circle hunt around your house. First point out a few examples, and then give your child a piece of paper and ask her to make a mark for each circle she finds. At the end of the hunt, count them up!

  • July 19: Sock Weights

    Gather up a collection of small items of varying weights and two socks. Ask your child to choose two items and put one in each sock. By feeling the weight of each sock, can he tell you which item is heaviest? Then "weigh" two more items. Ask older kids to put the items in order from lightest to heaviest.

  • July 20: Moon Day

    The first person to step on the moon did so on this day back in 1969. The journey to the moon started with a countdown to lift-off from Earth. Ask your child to pretend she is in charge of the launch and has to count backward from 20, 19, 18… all the way to lift-off!

  • July 21: Blast Off!

    3, 2, 1, blastoff! Count backwards in this online game to launch rockets with Curious George.

  • July 22: Pizza Match

    Make a mini pizza by spreading half an English muffin with tomato sauce and sprinkling it with cheese. Add whatever toppings you want (e.g., green pepper, black olives, pepperoni). Challenge your child to make a mini pizza that looks just like yours. Then ask him to make a pizza for you to copy.

  • July 23: One-Piece Puzzles

    Fold five sheets of paper in half. At the fold line, cut a shape out of the center of each piece of paper (e.g., heart, star, square). Now you have five one-piece shape puzzles! Put the shape cut-outs in one pile and the pieces of paper in another. Challenge your child to put the shape puzzles back together.

  • July 24: More Puzzle Fun

    Ask your child to find a full-page picture in a magazine. Glue it to a piece of heavy paper such as construction paper or poster board. Create a picture puzzle by cutting it into five or six large pieces. Mix the pieces up and challenge your child to put the picture back together.

  • July 26: Number Search

    Write the numbers 1 - 10 on index cards, one number per card. Ask your child to draw a card, and search for that number on objects around the house (e.g., on a clock or TV, in a newspaper or magazine, on a calendar or cereal box). Then draw another card, and so on.

  • July 27: Sock Match

    Find five or six pairs of socks with different colors or patterns. Put them in a pile and mix them up. Challenge your child to sort the socks and find all the matching pairs.

  • July 28: Size Hunt
