BINGO
Subtraction to 20

1) The teacher or the parent pulls out a subtraction card to 20 and call out the subtraction problem.

2) If the result of the subtraction matches any of the numbers in the table, mark that box with a star or cross it out.

3) The aim of the game is to get five marked fields in a row (horizontally, vertically,
or diagonally). The central square is counted as marked.

4) The first player who has five stars calls out "BINGO!" and is declared the winner.
