Play Bowls and Pennies
Contributed by linzy

Write the numbers 1 through 5 on small pieces of paper and stick them as labels on different bowls.  Give your child some pennies and ask him to put the right amount of pennies on each bowl as labeled.  You can also play variations of this game by placing the pennies in the bowl yourself and asking your child to label the bowls according to the number of pennies in them.

Use a makeshift basketball hoop for target practice - all you need is a bin and about 10 soft bean bags or scrunched balls of paper. Throw the paper balls and try to put them in the bin, counting the number of balls that goes inside and the number of times you missed.

Sing Math Songs
Contributed by linzy

There are a lot of songs you can sing which have math concepts in them: "One, two, three, four, five once I caught a fish alive...", "1, 2, buckle my shoe...", "1 potato, 2 potato," etc.  Adding actions to these songs will make it so much more fun to sing, and your child will learn to count in a joyous manner.
