Fractions: parts and wholes

In this lesson, we will learn about fractions through the context of part and whole modelling. We will practise using the terms 'part' and 'whole' correctly in sentences to model fractions. Resources provided by NCETM (CC BY-NC-SA: https://creativecommons.org/licenses/by-nc-sa/4.0)

Explore the whole and part relationship in familiar contexts, using area, linear and quality models

In this lesson, we will continue to learn about fractions through the context of part and whole. We will also think about whether stating that a part is smaller than the whole is true or false. Resources provided by NCETM (CC BY-NC-SA: https://creativecommons.org/licenses/by-nc-sa/4.0)

Explore the whole and part relationship and generalise that a part is always smaller than the whole

In this lesson, we will explore the concept of 'equal' and 'unequal' parts demonstrated through a rectangle separated into parts. Resources provided by NCETM (CC BY-NC-SA: https://creativecommons.org/licenses/by-nc-sa/4.0)

Explore the Concept of 'Equal' and 'Unequal' Parts

In this lesson, we will explore the concept of 'equal' and 'unequal' parts demonstrated through three strips of paper. We will look at shapes and decide if they have been separated into equal or unequal parts. Resources provided by NCETM (CC BY-NC-SA: https://creativecommons.org/licenses/by-nc-sa/4.0)

Embed the concept of equal parts and unequal parts

In this lesson we wil think about a set of objects as a whole, split them into parts and work out if they are equal or unequal. Resources provided by NCETM (CC BY-NC-SA: https://creativecommons.org/licenses/by-nc-sa/4.0)

Develop understanding that equal sized parts do not have to look the same

In this lesson, we will compare the size of parts using the language 'smaller and 'larger'. This will be demonstrated through filling glasses with water Resources provided by NCETM (CC BY-NC-SA: https://creativecommons.org/licenses/by-nc-sa/4.0)

Compare the size of parts when the whole is defined using familiar contexts

In this lesson, we will explore the concept that the size of the part is relative to the size of the whole using familiar concepts, such as filling glasses or containers with liquid. Resources provided by NCETM (CC BY-NC-SA: https://creativecommons.org/licenses/by-nc-sa/4.0)

Explore that size of part is relative to the size of the whole using familiar contexts

In this lesson, we will consider part and whole relationships within the context of quantity models. Resources provided by NCETM (CC BY-NC-SA: https://creativecommons.org/licenses/by-nc-sa/4.0)

Consider part whole relationships within the context of quantity models

In this lesson, we will work out how many equal and unequal parts the whole has and if we can build a whole once we know a part. Resources provided by NCETM (CC BY-NC-SA: https://creativecommons.org/licenses/by-nc-sa/4.0)

Build a whole when a part is known

In this lesson, we will investigate the ways we can build a whole once we know the size of one equally divided part.. Resources provided by NCETM (CC BY-NC-SA: https://creativecommons.org/licenses/by-nc-sa/4.0)
