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.

Relationship between the 3 and 9 times tables

Which calculation does the image represent?

If I know 3 × 9 = 27, then I know 9 × 9 = {{ }}

Match the groups of threes to the groups of 9 with the same value.

If Izzy has 15 sweets and Andeep has triple the amount, how many sweets does he have altogether? {{ }} sweets

Select the correct expression for this image.

Fill in the gap. Multiples of 9 are triple the multiples of {{ }}.

Which numbers are both multiples of 3 and 9?

Look at the bar model and fill in the blanks.

If Andeep’s mum has a total of 54 desserts, how many packs of 9 is this? How many packs of 3 is this?

If Izzy’s mum has a total of 99 desserts, how many packs of 9 is this? How many packs of 3 is this?
