## Add and subtract fractions with the same denominator

• Year group: Year 4
• Term: Spring
• Topic: Fractions
• Duration: 2 weeks
• Keystage: KS2
• Age Range: 8 to 9 yrs
• Unit can be taught out of sequence: N
• Week Range: 7 - 8

In this chapter, pupils build on their understanding of the addition and subtraction of fractions with the same denominator within one whole, by working with fractions that are greater than one whole.

To further develop pupils’ understanding of what happens when adding and subtracting fractions from chapter 4, they should use different concrete examples and visual representations.

It is essential that pupils are not just told to “add the numerators” and “keep the denominators the same”. They should be able to explain, using diagrams, how they have come to an answer when adding or subtracting two given fractions.

## Resources for this topic

### White Rose Maths

#### Adding fractions with the same denominator

These resources give children the opportunity to practice fluency, reasoning and problem solving questions.

#### Fractions with the same denominator

Direct link to our Y4 scheme.

### Mathematics Mastery

#### Add and subtract fractions with the same denominator

Mathematical discussion is a key element of the Mathematics Mastery programme.
Talk Tasks are a brilliant way of enabling pupils to develop their mathematical language, thinking, understanding and confidence.
This activity explores the concept of adding and subtracting fractions.
• Talk tasks are best completed in mixed attainment pairs, with pupils taking turns to listen and construct arguments
• Emphasis is on discussion rather than the solution, encouraging pupils to use key language and talk in full sentences
• Ask pupils to prove their answers in a variety of ways, using the CPA approach to support mathematical understanding and number sense

Select ‘View more’ for an accompanying video.

Enabling teachers to continuously develop their practice is a key element of the Mathematics Mastery Programme.

This CPD video provides step-by-step guidance on adding and subtracting fractions with the same denominator.

Our videos aim to:

• Model teaching tips, techniques and clarify how to make connections between concrete, pictorial and abstract representations
• Support the teaching of different methods and concepts, rather than focusing on one method only
• Enhance subject knowledge and support non-specialists

#### Adding and subtracting fractions (differentiated)

Two worksheets to help practise adding and subtracting fractions. Worksheet 1 concentrates on fractions with the same denominators. Worksheet 2 has fractions with different denominators.

#### Adding fractions- same denominator- fluency, reasoning and problem solving

A worksheet split into three steps to deepen children's understanding through varied questions. Children have to answer questions about adding fractions in different ways to start to show they have mastered the concept. Children could cut out each section and stick into their books, answering underneath, to show their steps in learning clearly.

#### Adding and subtracting fractions (different denominators) - mastery worksheet

This is a mastery worksheet involving adding and subtracting fractions with different denominators.

The worksheet is split into 3 sections, fluency, reasoning and problem solving so students can master the topic.

All answers are included for the questions.
