Number bonds to 20 snap

This is a great way to practise number bonds at speed. One player turns over a card and places it on the table, face up. The next player puts down a card next to it. Players take turns putting cards on the second pile (face up). When two cards put down together make 20, it’s snap! The person who says “snap” first keeps all the cards. Play again. The winner is the player who has all the cards at the end of the game.
