Today we touched on Fact families which will be discussed in more depth next week. Fact families are wonderful for showing how multiplication and division are related. They are simply all of the possible division and multiplication equations that are possible with a specific set of numbers.
For example:
The fact family for the numbers 7, 3, and 21 is:
3×7=21 7×3=21 21÷7=3 21÷3=7
We have already gone over changing to the inverse (or opposite) problem many times, so the students know how to go from multiplication to division and vice versa.
The purpose of this is to show how multiplication and division are related which also helps them to identify and solve for unknown numbers.
