Working with fractions

Lessons (20)

• In this lesson, we will learn how to divide a shape into equal parts in different ways. We will also discuss the vocabulary and sentences we can make when describing the shape and its parts.
1 Video
• In this lesson, we will learn to understand fraction rotation to help represent the relationship between the part and the whole. This can be demonstrated through usage of division bars.
1 Video
• In this lesson we will begin to use and understand the terms 'numerator' and 'denominator' alongside the language learnt in previous lessons.
1 Video
• In this lesson, we will learn to name unit fractions and match them with the fraction notation and a picture representation using the same language learnt in previous lessons.
1 Video
• In this lesson, we will investigate fractions using strips of paper and lines. We will use mathematical sentences to describe how many equal parts a whole strip of paper has been folded into, and what fraction each folded segment represents.
1 Video
• In this lesson, we will investigate how to determine the size of fractions in a 3D space. For example, we will determine what fraction of a stack of cubes is yellow.
1 Video
• In this lesson, we will continue to learn to assign fraction names and notation to equal parts of quantities. We will build on part-whole relationships by identifying fractions of sets.
1 Video
• In this lesson, we will recognise and reason about unit fractions in a variety of contexts. We will study a number of visual representations of different unit fractions.
1 Video
• In this lesson, we will look at whether equal parts of the whole always need to look the same. We will compare different representations of fractions using the same original whole.
1 Video
• In this lesson, we will understand that the same fraction can look different in the context of shading shapes with different volume or area. We will also investigate how a shaded fraction can look different but be the same proportion in the same shape if we make it in different ways.
1 Video
• In this lesson, we will compare unit fractions using a fraction wall. We will investigate the relative sizes of different unit fractions by comparing them side by side on a fraction wall.
1 Video
• In this lesson, we will further investigate how the deminominator tells us how many different equal parts there are and also tell us the size of the equal parts compared to the whole.
1 Video
• In this lesson, we will compare unit fractions using capacity and measurement to help us. We will use quantities of liquid in containers to help us compare the relative size of each unit fraction.
1 Video
• In this lesson, we will compare unit fractions of different wholes. We will investigate how a half is proportional to the size of the original whole, and that in turn, half of one object can look bigger or smaller than half of a different object.
1 Video
• In this lesson, we will take unit fractions of shapes and build the original whole from them. We will use mathematical sentences to describe how many of each fraction makes up the whole.
1 Video
• In this lesson, we will build and compare different wholes from unit fractions that represent the same length. We will use our knowledge of unit fractions to determine which whole line will be longest.
1 Video
• In this lesson, we will build and compare different wholes from the same unit fractions that represent different lengths. We will learn how finding out the length of one part can help you to find the length of the whole.
1 Video
• In this lesson, we will learn how finding out the amount of one part can help you to find the amount of the whole and how we can compare different wholes using the same amount but different fractions.
1 Video
• In this lesson, we will learn to build and compare different wholes from different unit fractions that represent different quantities. We can compare different wholes using the same fraction
1 Video
• In this lesson, we will build and compare different wholes when different unit fractions represent different amounts.
