Construct means to make or build something. In the context of this lesson, it means to make or build a whole from equal parts.

Constructing a whole

Maths

Use knowledge of the relationship between parts and wholes to solve problems

Use parts and wholes to find a unit fraction of a set of objects

Calculate the value of parts and wholes using understanding of division

Connect division with finding a fraction of a quantity to find parts and wholes

In this unit pupils will quantify the number of items in each part and connect to the unit fraction operator They will calculate the value of a part by connecting knowledge of division and division facts with finding a fraction of a quantity In the future unit pupils will explain that non-unit fractions are composed of more than one unit fraction using knowledge of unit fractions to find one whole

In the prior unit pupils compared and ordered unit fractions by looking at the denominator. In this unit pupils will quantify the number of items in each part and connect to the unit fraction operator. They will calculate the value of a part by connecting knowledge of division and division facts with finding a fraction of a quantity.

Calculate the value of a part (fractions as operators)

When we make or build something, we {{ }} it.

One red rod is one-sixth of the whole. Which representation shows a part alongside its whole?

One blue bar is twice the length of one green bar.

One blue bar is three times the length of one green bar.

One green bar is three times the length of one blue bar.

Which statement describes the relationship between the blue bar and the green bar?

If a part is one-eighth of the whole. How many equal parts are there in the whole?

Complete the sentence. If one-quarter is a part, then the whole is {{ }} times as much. Take {{ }} parts and put them together to make one whole.

Complete the table - what would be the number of equal parts in the whole?

Some, but not all of something, is known as a {{ }}.

If a whole is divided into two equal parts, each part is one-{{ }} of the whole.

If a whole is divided into four equal parts, each part is one-{{ }} of the whole.

Which image shows one-third of the whole bar?

A rod is one part of the whole. Five equal rods make up the whole. Which image shows the whole?
