Lesson details

Key learning points

When you compare two 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 combine to make a whole.

Common misconception

Children may think that fractions that look different cannot represent the same part of a whole. They may also still think that a bigger denominator means a bigger fraction.

Give plenty of opportunity to use manipulatives and representations to show sets and groups of objects divided in different ways so that they see practically that the same part of a whole can be described and represented by different fractions.

Use cubes or counters in the lesson to allow children to engage with the activities practically to build their understanding of different fractions labelling the same part of a whole and sitting at the same position on a number line.
