Pupils must understand one-hundreth in terms of regrouping and exchanging.
Dienes can be used to illustrate the relative size of 1 and one-hundreth, with a ‘flat’ representing 1.
Pupils should experience:
- how 100 hundredths can be regrouped into 1 one.
- how to exchange 1 one for 100 hundredths.
Language focus “100 hundreths is equal to 1 one.”
Pupils must then be able to work out how many hundreths there are in other multiples of 0.01
Language focus “18 hundredths is equal to 0 ones and 18 hundredths, and is written as 0.18.”
