# Slap Jack

#### Learning Outcomes

Subtraction through identifying a difference of one.

#### Instructions

**1.** Each player has one deck of 20 cards which he shuffles.

**2.** Both player #1 and player #2 turn over a card.

**3.** Both players are looking for two cards that have a difference of 1.

When this occurs, the players slap their hands on the table and say

“ONE!”

**4.** The player who slaps first (his or her hand will be on the bottom if both

players slap together) gets all the cards turned up in both players’ piles.

If a player says “ONE” incorrectly, the other player gets the cards.

**5.** Once all the cards in the two decks have been played, reshuffle and

start again.

**6.** Play continues until one player has won all the cards or a time limit

(5 minutes) has been reached.

###### Modification

Once the child has mastered Slap Jack 1, you can make this game slightly more challenging by changing the objective to finding a difference of 2, 3, 4, etcetera.
