Unit Summary
In this unit pupils will identify equal parts when they do not look the same related to equivalence. They will construct a whole when given a part and the number of parts.
Lesson Summary
You will learn to identify a whole and the parts that make it up.
Key Notes
- An item can be a whole or a part depending on the situation.
- Use of 'If the ___ is the whole, then the ___ are a part of the whole.' supports us to identify the whole and parts.
- The whole can be different in different situations.
- A part is always smaller than the whole.
Vocabulary To Learn
- Whole: The whole is all the parts or everything, the total amount.
- Part: A part is some, but not all, of the whole.
Common Mistakes To Avoid
- Pupils might think that larger objects cannot be a part of a whole due to their size. Children may not appreciate that the same item can be a whole or a part depending on the context.
3 Quick Questions (With Answers)
1. Solve this in steps: explain the method from this lesson and why each step matters.

The whole is all the parts or everything, the total amount. Use this word when showing your method, then check your final answer is reasonable.
3. Spot and fix this common maths mistake.
Mistake: Pupils might think that larger objects cannot be a part of a whole due to their size. Children may not appreciate that the same item can be a whole or a part depending on the context. Correction: Encourage pupils to work with parts and wholes that they can handle and experience but where parts are large and have them look at example where the same object can be a whole or a part.
