Multo is like Bingo, but better! The teacher uses 100 cards marked from 0x0 through to 9x9. Students draw up a 4 row / 4 column grid and enter 16 numbers which would be answers to these cards. To begin with, no repeats are allowed. The teacher draws cards one at a time and, at a regular pace, announces each random times table in turn. If students have the answer on their grid, they mark it off. Multo is either: 4 in a row horizontally, 4 in a row vertically, 4 in a row diagonally, or all four corners. The game involves plenty of times tables practice but this is soon subservient to the greater challenge of finding the best Multo grid. Software aids the search. The linked assessment sheet provides teachers with considerable assessment information.
