Learn about grouping 10's and 100's and compare 2 and 3 digit numbers.

Take a deck of cards and play "WAR." Each player turns over one card. Have your child determine who has the larger number and that player keeps both cards. Continue until one person has all the cards. If both players have the same number, leave those cards down on the table and turn over another card to determine who keeps all the cards on the table. Other ideas: have your child add the two numbers that each player turns over or have your child start with the largest number and subtract!
