An adjacent multiple is a multiple next to another. It could be before or after.

Solve problems involving adjacent multiples of nine

Maths

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

In the prior unit pupils explained the relationship between multiples of 3 and multiples of 6 using knowledge of the relationships between the 3x and 6x tables. In this unit pupils will represent counting in 9s as the 9x table explaining the relationship between adjacent multiples of 9. They will use known facts from the 10x table to solve problems involving the 9x table.

Represent counting in nines as the 9 times table

Lucas makes shapes using 9 sticks each time. He has made 3 shapes and used 27 sticks. Lucas makes another of the shapes. How many sticks has he used now?

There are 7 flowers with 9 petals each. If Jun gives away one flower, how many petals will there be altogether? {{ }} petals

Lucas has filled 7 buckets with 9 litres of water ready for a water fight. Jun brings one more bucket of water with the same amount. How many litres of water have they used altogether? {{ }} litres

Which multiple of 9 is missing from this sequence?
45, {{ }}, 63, 72

Which symbol goes in the gap to make this correct?
9 × 9 = 10 × 9 ___ 9

Which symbol goes in the gap to make this correct?
2 × 9 = 3 × 9 ___ 9 

Complete: I know that 3 × 9 = 27 so 30 × 9 = {{ }}

Complete: I know that 5 × 9 = 45 so 50 × 9 = {{ }}
