Numbers are equivalent if they have exactly the same value.

When one whole is divided into 10 equal parts, each part is one tenth. This can be expressed as a fraction or as a decimal.

When one whole is divided into 100 equal parts, each part is one hundredth. This can be expressed as a fraction or as a decimal.

Use knowledge of common equivalents to compare fractions and decimals

Maths

In this unit pupils will use representations to describe and compare two fractions. They will  explain the relationship within families of equivalent fractions and use their knowledge of common equivalents to compare fractions with decimals. In the future unit pupils will explain how to write a fraction in its simplest form when solving addition and subtraction problems. 

In the prior unit pupils will find unit and non-unit fractions of whole numbers and explore parts and wholes. In this unit pupils will use representations to describe and compare two fractions. They will  explain the relationship within families of equivalent fractions and use their knowledge of common equivalents to compare fractions with decimals.
