What is an even number?
Explain why we say the "usual" number of equations in a fact family and give an example of when it isn't the usual number
Since each fact family uses 3 numbers, we can usually write 4 different equations with them (2 multiplication and 2 division). When the factors are the same though, there will only be 2 equations. For example:
5,5,25- 5x5=25 and 25/5=5
21 divided by 3 =

The rule that tells you if a dividend can be divided by 6
What is if the dividend can be divided by both 2 AND 3
7 divided by 0
