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 how many equal parts a whole as been divided into.
Key Notes
- The whole has been divided into __ equal parts.
- The whole can be one shape or a group of objects.
- A whole can be divided into equal parts in different ways.
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
- Children may have difficulty identifying the number of parts when dealing with cardinality and quantity. For example, dividing a class up into equal groups.
3 Quick Questions (With Answers)
1. Solve this in steps: explain the method from this lesson and why each step matters.
The whole has been divided into __ equal parts. The whole can be one shape or a group of objects.
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: Children may have difficulty identifying the number of parts when dealing with cardinality and quantity. For example, dividing a class up into equal groups. Correction: Use a bar model to show a number of children being divided into equal parts. The bar model will then link to the paper strips in the slides.
