## Lesson details

### Key learning points

1. The whole is divided into ten equal parts and one of them is one tenth of the whole.
2. There are ten tenths in one whole.
3. One whole can be divided into ten tenths.

### Common misconception

Pupils think one tenth consists of one shaded part and ten un-shaded parts.

Encourage children to use the stem sentence to identify the whole and how many parts make it up each time.

### Keywords

• Equal - Equal means exactly the same amount or value.

• Tenth - A tenth is the name we give to one part of ten equal parts.

Focus on providing children with the opportunity to generalise what one tenth is in lots of different contexts. It is important that they see it in area, linear and quantity examples.
