Help your primary learners develop an understanding of the concept of one more and one less using two sets of number cards. The first set of cards, all in one color, is the "one less" deck. The second set, again all in one specific color, is the "one more" deck. After a demonstration of the game, working in trios or pairs, learners play the game trying to win pairs. The player with the most pairs wins. A fun math center or a game for young learners to sign out and play with a sibling or parent at home.
