Unit Summary
In this unit pupils will represent unit fractions in different ways, identifying the whole, the number of equal parts and the size of each part as a unit fraction, including tenths.
Lesson Summary
You will learn to identify the number of equal or unequal parts in a whole.
Key Notes
- Parts can be equal or unequal in size.
- There are __ equal parts in the whole.
- There are __ unequal parts in the whole.
Vocabulary To Learn
- 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.
Common Mistakes To Avoid
- Sometimes parts can be deceptive and look equal but are in fact unequal. For example, the rhombus that has been split into parts with lines that are equally distributed.
3 Quick Questions (With Answers)
1. Solve this in steps: explain the method from this lesson and why each step matters.

2. Use this key word in a maths sentence and explain it clearly. 'Whole'
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: Sometimes parts can be deceptive and look equal but are in fact unequal. For example, the rhombus that has been split into parts with lines that are equally distributed. Correction: Explore this further by presenting several examples like this if needed. You could ask the children to try and think of some examples where the parts look equal but are in fact unequal. Getting the children thinking of this will boost understanding.
