Math Activity Calendar: March

  • March 1: Peanut Butter Lovers Day

    Make peanut butter and jelly sandwiches, but with a math twist. If your child can't eat peanut butter, use cream cheese instead. Use cookie cutters or a knife to make shape sandwiches.

  • March 2: Dr. Seuss's Birthday

    Celebrate Dr. Seuss's birthday by playing a shape game with The Cat in the Hat.

  • March 3: Ramp and Roll

    Get a small ball and two books. Put something under one end of a book, so it slants to form a ramp. Put something bigger under the other book, so it slants even more. Measure how far the ball rolls down each of the ramps. Compare the distances. Ask your child, "Why did one ball roll farther than the other?"

  • March 4: Find the Day

    What day of the week does March 31 fall on? Give your child a calendar to find out. What about the last day of next month?

  • March 6: What's in the Bag?

    Get five objects that are easy to tell apart. Show your child the objects. Talk about what they are and count them together. While your child's eyes are closed, put two of the objects in a bag. Ask her, "How many are in the bag?" and then "What is in the bag?"

  • March 7: Scoop and Guess

    Fill a bowl with cereal that is made up of pieces that are the same size, such as Cheerios. Ask your child to scoop out a spoonful and guess how many pieces of cereal are on the spoon. Now tell him to count them to check her guess.

  • March 13: Math on the Go!

    Counting games are a fun way to pass the time when you are on a car trip with your child. For example, see who'll be the first to find 10 trucks, 6 blue cars, or 9 hotels. You can also count out-of-state license plates.

  • March 14: More Math on the Go!

    Play a guessing game. Think of a number and give your child clues, such as, "I am thinking of a number between 10 and 40. You say it when you count by 10's. It is not 20.

  • March 15: Measuring Months

    Make a list of the months. The letters of each month should be directly under those of the previous month, so you can accurately compare their lengths. Give the list to your child and ask, "Which month has the longest name?", "Which has the shortest name?", and "Are any names the same length?"

  • March 16: Balancing Rocks

    Your child uses a pan balance in this online game to help May weigh different kinds of rocks in Sid the Science Kid's Super-Fab-Lab.

    Does March have more or less days than April? What about September? Give your child a calendar to find out.

  • March 20: First Day of Spring

    Celebrate spring by planting grass, but not in a garden! Make eggshell people with grass "hair." Give your child an empty eggshell with the top third removed. Ask her to draw a face on it. Fill it with potting soil and sprinkle grass seed on top. Keep the soil moist. When the "hair" begins to grow, measure it every few days.

  • March 21: Growing Up and Down

    Introduce your child to spatial vocabulary such as under, above, up, and down . Talk with your child about how some plants grow down, under the ground (e.g., carrots and potatoes) and some plants grow up, above the grown (e.g., corn and tomatoes).

  • March 26: Minute Run

    If it's a nice day, your child can get some exercise and also learn about measuring time. On your driveway or sidewalk draw a chalk line. Draw another one about 12 feet away. Tell your child you want her to run back and forth between these lines for a minute.

  • March 27: Number Order

    On index cards, write the numerals from 1 to 10 (one numeral per card). Mix them up and spread them out on a table. Ask your child to line the numerals up in order from smallest to largest. Then ask her to line them up from largest to smallest.

  • March 28: Matching Numbers

    On index cards, write the words for the numbers 1 to 10, one number word per card. On another set of index cards write the numerals for the same numbers. Invite your child to match the numerals to the words ( e.g., "7" to "seven"). For younger kids, use dots instead of words.

  • March 29: Number Memory

    Turn all 20 index cards from yesterday's activity face down. Invite your child to play a number memory game. Ask him to turn over two cards at a time and find all the numeral/number word pairs (e.g., the card with the "7" is a match for the card with the number word "seven".

  • March 30: Pencil Day

    Today is National Pencil Day! The pencil was invented in 1895. The pencil also makes a great measuring tool if you don't have a ruler handy. Ask your child to use a pencil to measure his bed. Then have him measure the bed with something else of a different length, a book for example. Why are the measurements different?

  • March 31: Number Riddles

    Play a number riddle game with your child. Say, "I am thinking of a number. When you add "1" to it , you get "6". What's my number?" Now ask your child to think of a number riddle for you to solve.
