This is a great game to play with nothing more than a deck of cards and two or more players. The parent should be the dealer and the children should be the players. The dealer names which color should be slapped, either red or black. As the dealer flips over cards from the deck, the players should attempt to be the first to slap any cards of the named color. The first to slap the card gets to keep the card. If a player slaps a card that is the wrong color that player loses all of his or her cards. When the dealer finishes the deck the players should count their cards. The player with the most cards wins.
For players that are a bit beyond acknowledging colors, modify this game to odd or even numbers or multiples of a chosen number.
