Lesson details

Key learning points

When you compare fractions, the whole must be the same.
Use representations of sets of objects to divide them into equal parts.
Count how many objects are in the number of parts needed.
The whole has been divided into __ equal parts and you have __ of them.

Keywords

Divided - When something is divided, it is split into equal parts or groups.
Equal parts - Equal parts can be combined to make a whole.
Numerator - The numerator is the top number in a fraction and shows how many equal parts we have.
Denominator - The denominator is the bottom number in a fraction and shows how many equal parts the whole has been divided into.

Common misconception

Children may still be building understanding that the same fraction can be represented and recorded in different ways. They may still think that the larger the denominator, the larger the fraction.

Make use of the stem sentences to support understanding of how the recording of the fraction relates to the images and contexts used. Model the use of the keywords numerator and denominator and encourage children to use them in explanations.

Continue to use practical resources where possible so that children can create and describe equal groups using different fractions. Make the lesson as practical as possible before encouraging children to record fractions which represent the same proportion using the = symbol.
