Multiplication and division tables (2,3,5,10)
Lesson
Sometimes, we need to use a mixture of multiplication or division to solve problems. In these examples we'll look at one problem in different ways, to see how multiplication and division are related. This allows us to work out how to fill in the missing values in a multiplication and division table. This means we are using our 'fact families' to help us solve multiplication and division problems.
