Lesson details

Key learning points

Parts of the same sized whole can be compared.
A bigger or smaller part of the whole can be shown.
Different parts of the same sized whole can be directly compared based on their size.

Common misconception

The part changes size when the whole changes.

Use the bottles example in the slides to overcome this. Have a range of different sized containers for water and demonstrate the concept practically.

Keywords

Whole - The whole is all the parts or everything, the total amount.
Part - A part is some of the whole.
Equal - We say that two or more things are equal if they have the same quantity or value.
Unequal - We say that two or more things are unequal if they do not have the same quantity or value.
Inequality - Inequality occurs when things are not equal. We use different symbols to show this.

Use plenty of real practical examples here. You might want to get some water bottles to use! Some of the contexts (maps of Europe or the UK) may not be relevant in your context so choose something different to engage the children you teach.
