Know that 10 tenths are equivalent to 1 one, and that 1 is 10 times the size of 0.1 (5)

Description

Pupils must understand one-tenth in terms of regrouping and exchanging.

Dienes can be used to illustrate the relative size of 1 and one-tenth, with a ‘flat’  representing 1.

Pupils should experience:

• how 10 tenths can be regrouped into 1 one
• how to exchange 1 one for 10 tenths

Language focus “10 tenths is equal to 1 one.”

Pupils must then be able to work out how many tenths there are in other multiples of 0.1

Language focus “ 18 tenths is equal to 1 one and 8 tenths and is written as 1.8. ”
