## Introduction

The Fractions spine is divided into 10 segments. For each of these segments we have produced a detailed teacher guide, including text and images. The images are also presented as animated PowerPoint slides, which further enhance teacher knowledge and can be used in the classroom (for best results, please view these in ‘Slideshow’ view; for some slides, supporting notes are provided in the ‘Notes’ section). These materials are not, in any way, lesson plans, but they can be used in conjunction with a high-quality mastery textbook to support planning. Click on the ‘+’ signs below to view the materials.

## 3.1 Preparing for fractions: the part–whole relationship

Identify parts and wholes of areas, lengths and sets. Identify equal and unequal parts; make judgements about the relative size of a part to a whole. Find the whole when the size of a part and number of equal parts is known.

## 3.2 Unit fractions: identifying, representing and comparing

Learn to name and write unit fractions. Recognise and show unit fractions of areas, lengths and quantities. Relate numerators and denominators to parts and wholes; explore how the greater the denominators, the smaller the unit fraction.

## 3.3 Non-unit fractions: identifying, representing and comparing

Learn to name and write non-unit fractions, recognising them as multiples of unit fractions. Learn that fractions are numbers that can be positioned on a number line. Compare and order fractions with the same denominator or same numerator.

## 3.4 Adding and subtracting within one whole

Explore how to add and subtract fractions within one whole where the denominators are the same. Apply prior knowledge of the inverse relationship of addition and subtraction with whole numbers, to fractions.

## 3.5 Working across one whole: improper fractions and mixed numbers

Meet mixed numbers and improper fractions, and learn to convert between them; compare, order and place them on a number line. Extend addition and subtraction from within a whole to numbers greater than one whole.

## 3.6 Multiplying whole numbers and fractions

Consider multiplication of whole numbers and proper fractions as both repeated addition and scaling. Understand that multiplication of a whole number by a proper fraction results in a smaller number.

## 3.7 Finding equivalent fractions and simplifying fractions

Discover how equivalent fractions have the same proportional relationship between the numerator and denominator, and therefore have the same numerical value. Convert between equivalent fractions and simplify fractions.

## 3.8 Common denomination: more adding and subtracting

Learn to add and subtract fractions with different denominators by first finding a common denominator. Compare fractions using a range of methods, including converting to a common denominator.

## 3.9 Multiplying fractions and dividing fractions by a whole number

Explore how to multiply two fractions. Learn how to divide a fraction by a whole number by first converting to an equivalent multiplication. Review how multiplying by a proper fraction makes a number smaller.

## 3.10 Linking fractions, decimals and percentages

Make connections between fractions and previous work on decimals. Learn common fraction and decimal equivalences. Understand that percentages tell us about the proportion being considered. Find percentages of quantities.

Hi dltrinder, you'll be best to keep an eye on this page. We can't guarantee that that will get specifically announced.

We will produce guidance for KS1 once all the fraction segments have been published for KS2. This will draw on what is in Y3. All of the faction requirements of the primary curriculum are covered in the KS2 materials. We made the decision to focus on KS2 to address fractions in a ‘mastery way’.

The NC has sections in KS1 for fractions. In year 2 I would use some areas of the Year 3 spine eg parts and whole and equal parts.
