Hundredths (age 8+)
Count up and down in hundredths; recognise that hundredths arise when dividing an object by 100 or dividing tenths by 10
What a learner can do afterwards
- Count from 3/100 to 12/100 in hundredths
- Explain that 1/10 ÷ 10 = 1/100
- Place several hundredths on a number line between 0 and 1/10

You already know tenths, so hundredths will feel familiar. If you cut a whole into 100 equal parts instead of 10, each part is called a hundredth. We write it as 1/100.
Ravi has £1, which is the same as 100 pennies. He spends 8 pennies, so he has spent 8 out of 100 parts of his pound. That is 8/100.
Counting hundredths works just like counting whole numbers, only the bottom number stays 100. After 9/100 comes 10/100, then 11/100, and so on, all the way up to 100/100, which is one whole.
A hundredth is one part when a whole is split into 100 equal pieces, and you count them one by one just like whole numbers.
