Each player, in turn, turns over his top card and checks to see if his card plus the top discard will total five. If the two cards total five, the player wins the pair. The person with the most pairs wins the game. In another game, Knock Knock, players try for the largest total possible with four cards. Each player is dealt four cards with the remaining cards in the draw pile.
Players take turns drawing the top card from the draw pile and discarding one card.
When a player thinks he or she has the largest total, the player says Knock-Knock. Everyone else has one more turn and then the totals are added. Also included in this set are games for evaluating more and less, sequencing numbers, and forming sets. The games are from C. Kamii class notes, 1990. All instructions are included.
