Play cards together with your child. An easy game to reinforce basic skills is WAR. Divide the deck equally between you and your child. Players do not look at their cards and keep the face down in a stack. Each player turns over one card at a time simultaneously. The first player to call out the sum of the two cards gets to keep the set. The player with the most cards at the end of the game wins. There are many variations of this game where you can assign different values to the face cards or even multiply the numbers instead of adding them. Have fun!
