Unit Summary
In this unit pupils will identify whether something has or has not been split into equal parts. They will name fractions one-half one-quarter and one-third in relation to a fraction of a length shape or set of objects.
Lesson Summary
You will learn to name the fraction 'one-third' in relation to a fraction of an object, shape or set of objects and explain how you know that it is a third.
Key Notes
- When the whole has been divided into three equal parts, each part is one-third of the whole.
- You can find thirds of objects, shapes and sets of objects.
Vocabulary To Learn
- Third or one-third: One of three equal parts of a whole. To divide into three equal parts.
Common Mistakes To Avoid
- Children can find it difficult to see if the three parts are equal, particularly when they are presented in different orientations rather than horizontal and vertical lines.
3 Quick Questions (With Answers)
1. Solve this in steps: explain the method from this lesson and why each step matters.
When the whole has been divided into three equal parts, each part is one-third of the whole. You can find thirds of objects, shapes and sets of objects.
2. Use this key word in a maths sentence and explain it clearly. 'Third or one-third'
One of three equal parts of a whole. To divide into three equal parts. Use this word when showing your method, then check your final answer is reasonable.
3. Spot and fix this common maths mistake.
Mistake: Children can find it difficult to see if the three parts are equal, particularly when they are presented in different orientations rather than horizontal and vertical lines. Correction: Allow children to handle practical objects and cut-outs of shapes that have been divided into thirds so they can rotate them and see them in different orientations.
