These cards are Multiplication Bingo Cards. They consist of numbers between 0 and 9. You will find multiplication operations such as 7*5, 2*2 and even 0*0.
A good idea to spark extra thinking would be to call the multiplication result. For instance if the multiplication operation that is listed to be called is "2*4" then call "8" instead. Just notice that many other possibilities (like 1*8) can appear. Create the printable multiplication bingo cards by clicking the blue "Generate Bingo Cards" button.
