Explain the relationship between pairs of 3 and 9 times table facts that have the same product

Maths

In this unit pupils will explain the relationship between multiples of 3 and multiples of 9 and use it to solve problems.  In the future unit pupils will represent counting in sevens as the 7x table explaining the relationship between adjacent multiples of 7 and knowledge of the 7x table to solve problems 

In the prior unit pupils represented counting in nines as the 9x table explaining the relationship between adjacent multiples of 9. They used known facts from the 10x table to solve problems involving the 9x table.  In this unit pupils will explain the relationship between multiples of 3 and multiples of 9 and use it to solve problems.
