  • January 1: New Year's Day

    Being the "first" day of the "first" month of the new year, today is a good day to introduce your child to ordinal numbers such as "first", "second", and "third". What are the "second" and "third" months of the year? What position is your child's birthday month?

  • January 2: Birthday Math

    Ask your child to find her birthday on the calendar and tell you what day of the week it falls on this year. What about the birthdays of other family members?

  • January 3: More Birthday Math

    Use a calculator to figure out how many months old your child will be on his birthday this year. Remind him there are 12 months in a year, so he has to add 12 for each year of his age.

  • January 4: Spaghetti Day

    Make pasta patterns. Get two or three different pasta shapes (e.g., elbow, bowtie, pinwheel). Start a pattern and ask your child to finish it (e.g., bowtie — elbow — bowtie — elbow — bowtie — ?). Challenge your child to come up with her own pattern .

  • January 5: Let's Compare!

    Create two groups of objects, one with five items and the other with four items (use more items for older kids). Ask your child to look at both groups and tell you which one contains more and which has less? Then ask, "How many more?" and "How many less?"

  • January 6: Make a Snowman Day

    You don't have to have snow to make a snowman! Cut out three different sized circles from white paper. Ask your child to glue them onto a sheet of dark paper, stacking them in order of biggest to smallest. Now give the snowman a face, hat, and scarf.

  • January 7: Number 7

    Ask your child how many ways he can make the number 7 (e.g. 5+2, 4+3, etc.). He can show you in a drawing, with groups of small objects such as coins, or by holding up fingers. There are lots of ways to make 7!

  • January 8: Rock & Roll Day

    Celebrate the day by playing rock music and challenging your child to dance for one minute. She'll have fun and will also experience how long a minute is, a difficult concept for young kids.

    Get nine pennies or other small objects. Ask your child to divide them up into three equal groups. How many are in each group?

  • January 10: Decade Count

    See how far your child can count by 10's (or decades). Can she count to 50? 100? 200? More?

  • January 11: Palindrome Numbers

    The number 11 is a palindrome, which means it is the same if you read it forward or backward. Ask your child if he can tell you some other numbers that are palindromes (e.g., 22, 33, 222, etc.).

  • January 12: Secret Number

    Think of a number between 1 and 10 (20 for older kids) and challenge your child to guess your "secret" number by following clues such as "When you add 2 to my secret number you get 6," or "my secret number is bigger than 3 but smaller than 5."

  • January 13: More Secret Numbers

    Invite your child to think of a secret number between 1 and 10 for you to guess. Ask him questions such as, "Is your secret number larger than 5?", "Is it smaller than 8?", etc.

  • January 14: Number Safari

    Think of a number, and then take your child on a safari around the house to find that number in as many places as possible (e.g., on clocks, phones, magazines, newspapers, etc.).

    How many days are left in January? Give your child a calendar, and ask him to count the remaining days.

  • January 16: Sweet 16

    Ask your child to tell you what day of the week the 16th falls on next month. What about in July? In November?

  • January 17: The Ten of Teens

    Show your child that the number 17 is made up of one "10" and seven "ones", or 10 + 7 = 17. Use pennies to represent this concept. Separate 17 pennies into one pile of 10 pennies and another pile of 7 pennies. Do the same for the numbers 18 and 19.

  • January 18: Winnie the Pooh Day

    Winnie the Pooh and his friends all live in the 100 Acre Wood. Explore the number 100 with your child. Ask her to count out 100 pennies, make a chain out of 100 paperclips, or string together 100 piece of elbow macaroni.

  • January 19: National Popcorn Day

    Fill a bowl with popped popcorn. Ask your child to grab a handful, and then guess how many piece she has in her hand. Now count them. Using what she knows about how many pieces she can hold in her hand, can she guess how many are in the whole bowl?

  • January 20: Location I Spy

    Use the classic "I Spy" game to help your child learn spatial relationships by giving clues about an object's location. Use position words such as above, under, on top of, next to, etc. For example: "I spy something purple under the table."

  • January 21: Sweetener Sort

    To pass the time at a restaurant, play a sorting game with the different colored packets of sweetener. Mix them up and ask your child to sort them by color. You can also create color patterns with them (e.g., yellow — pink — blue — yellow — pink — blue — yellow — pink — what comes next?)

    How many different kinds of shapes can your child make out of drinking straws?

  • January 24: More Foot Fun

    Measure your child's foot three ways (e.g., using paperclips, barrettes, and pennies), and compare the results. Using pennies, for example, line them up from the heel to the tip of the big toe. Count the pennies. Ask your child, "How many pennies long is your foot?"

  • January 25: Opposite Day

    Challenge your child to an opposites game. Take turns finding things that are small and big, tall and short, and narrow and wide. Start out by pointing to a short glass and saying, "Look, there is a short glass, can you find a tall glass?"

  • January 26: Let's Tessellate!

    Here's an online game your child can play to explore geometry by showing how shapes tessellate, or repeat to cover an area without gaps or overlaps. A honeycomb, for example, is made by tessellating hexagons.
