Lesson Details

Key learning points

There are one hundred hundredths in one whole.
There are ten hundredths in one tenth.
Unitising can help to multiply hundredths by whole numbers.
The sentence: ___ times ___ ones is equal to ___ ones so ___ times ___ hundredths is equal to ___ hundredths supports us

Common misconception

Children may get confused with the vocabulary when we say, for example, zero point one two rather than zero point twelve. They may also confuse how we write, for example, 32 hundredths.

We say zero point one two to show that there is one tenth and two hundredths. 32 hundredths is composed of 30 hundredths - this is the same as 3 tenths and we have 2 more hundredths so 32 hundredths is written 0.32

Keywords
