Multiplying and dividing by Multiples of 10 Multiplying and dividing Bingo! A bingo game on operations to multiply and divide using powers of ten. Questions are projected on the board. You can change the order of these if you want. Comes complete with printable unique bingo cards for up to 36 students. Alternatively, there is a no print option where students draw their own 3 by 3 grid and choose nine numbers from the board. If the answer to a slide is their number they cross it off. The first student who crosses off all nine numbers and calls out ‘bingo!’ is the winner.(For a speed version it can be the first to get a row or column). Usually there is a small prize for the winner.
