Here are three numbers: five, 40, and eight. Use only these numbers to make a different sentence each time. Five times eight equals 40. What times what equals what? And what divided by what equals what?
So we have to use the numbers five, 40, and eight to make two new number sentences. If we know that five times eight is 40, we could switch these two numbers around, because eight times five is also 40. It doesn’t matter which order we do the calculation in a multiplication. Eight times five is 40, and five times eight is 40. So we’ve completed our first number sentence. We found another multiplication fact using our three given numbers.
Our third sentence is a division sentence. So we can use our largest number first, 40, which means that 40 divided by five would be eight. We used the three numbers five, 40, and eight to make two new number sentences. Eight times five equals 40. 40 divided by five equals eight. We could’ve also written 40 divided by eight equals five.
