The game consists of a deck of cards, with each card featuring a number between 1 and 20. To play the game, players take turns drawing a card from the deck and placing it face-up in the center of the playing area. Players then take turns trying to find a card in their own hand that is one less or one more than the card in the center. For example, if the center card is a 5, players can play a 4 or a 6 from their hand.
If a player is unable to make a play, they must draw another card from the deck. The game continues until all the cards in the deck have been played or until one player runs out of cards in their hand. The player with the most cards at the end of the game is the winner.
One Less One More Card Game is a simple yet effective way to help young children develop their number sense, arithmetic skills, and strategic thinking abilities. By playing the game, children can practice identifying and comparing numbers, counting on and back, and recognizing number patterns. The game can be easily adapted to suit different skill levels and can be used in the classroom or at home as a fun and educational way to reinforce math concepts.
