How math bingo works
In math bingo the caller reads a problem such as "6 × 7" and the players mark the answer, 42. The cards hold answers, never problems, so every child has to work the fact out before marking it. A 5x5 card with a free space needs 24 different answers, a 4x4 card 16 and a 3x3 card 8 or 9, which is why small fact sets such as a single times table are printed on smaller grids.
Some answers belong to several problems: in the times tables from 1 × 1 to 12 × 12, 12 and 24 can each be made six different ways (12 is 1 × 12, 2 × 6, 3 × 4, 4 × 3, 6 × 2 or 12 × 1). Those answers are marked earlier in a game, on average, than answers with a single problem. Every set page lists its full answer key grouped by answer and shows how often each answer comes up, so you can decide whether to keep the set as it is or drop the repeated facts for a fairer game.
Choosing a set for your class
Pick the set your class is practicing this week rather than the hardest one it knows: bingo works best as quick recall. Early grades usually move from addition within 10 to make-ten bonds and addition within 20, then subtraction; third and fourth grades work through single times tables before the mixed tables to 10 and 12, and division follows each table. Small sets fill only a 3x3 or 4x4 card, so play them for a full card, and keep a whiteboard handy to show the worked problem after each call.
