Practice counting down from any double-digit number. For example, use a calendar to count down the number of days to an upcoming event.

Prepare for multiplication by helping your child think in groups. Ask “how many fingers do five people have?”

Try a variation on the card game “War.” When the higher card takes the lower card, subtract the lower number from the higher number, and the player who won that play wins those points.

Give your child the change in your pocket and ask how many different ways she can make 25 cents.

Play a variation on the game “Go Fish.” Instead of asking for cards with numbers that match, players take turns asking for cards that, added to the card she has, adds up to 10. Count face cards as zero, aces as 1’s.
