When two or more fractions share the same denominator, you can say they have a common denominator.

The magnitude of something refers to the size of something.

To be efficient means finding a way to solve a problem quickly whilst also maintaining accuracy.

Explain which strategy for comparing non-related fractions is most efficient

Maths

Explain how to compare non-related fractions finding equivalent fractions with common denominators

Explain how to compare pairs of non-related fractions by comparing to a half

Explain how to compare pairs of non-related fractions using fraction sense

Order sets of non-related fractions using a range of strategies

In this unit pupils will use their fraction sense to explain how to compare pairs of non-related fractions either by converting to common denominators or using fraction knowledge and understanding. In the future unit pupils will learn how to multiply 2 unit fractions and 2 non-unit fractions They will learn how to divide a unit fraction and a non-unit fraction by a whole number 

In the prior unit pupils explained how to write a fraction in its simplest form when solving addition and subtraction problems and added and subtracted related fractions.  In this unit pupils will use their fraction sense to explain how to compare pairs of non-related fractions either by converting to common denominators or using fraction knowledge and understanding.
