# Multiplications – 3x 6x 9x

This week in Maths we have been learning our 3, 6 and 9 times tables. Multiplication facts are really useful for helping us prepare for our understanding of doubling, halving, fractions and decimals.

Mr Lo was very impressed with everyone’s concentration.

At the beginning of the week, Mr Lo showed how pupils in China use their knowledge of multiplications being commutative (e.g 6×3 is the same as 3 x 6) to cut down the number of times tables to recall. (And Rocking Robins are already experts on understanding commutative multiplications ,Inverse operations! ( 3×9 = 27 so I know 27 ÷9 = 3) and fact families (3×9 = 27, 9 x 3 = 27 27÷9=3 27÷3 =9)

The idea is you keep track of the times tables you can recall within 6 seconds by colouring it in. Only colour in the times table if you can recall it within 6 seconds every time!

We also looked at how the 6x table can be worked out by doubling the 3x table

or by using the 5x table + the 1x table!

For example how can we work out 6×6?

Well we can say 3×6 = 18. so 6×6 = 18 + 18 = 36

Or we might say 5×6 = 30 so 6X6 =30+ 6 = 36!
