This pupil-friendly study guide includes a unit summary, clear notes, common mistakes, and quick questions with answers.
Unit Summary
In this unit pupils will use representations to describe and compare two fractions. They will explain the relationship within families of equivalent fractions and use their knowledge of common equivalents to compare fractions with decimals.
Lesson Summary
You will learn to recall common fraction - decimal equivalents.
Key Notes
- 0.1 is equal to 1/10
- 0.2 is equal to 1/5
- 0.25 is equal to 1/4
- 0.5 is equal to 1/2
- 0.75 is equal to 3/4
Vocabulary To Learn
- Equivalent: Numbers are equivalent if they have exactly the same value.
Common Mistakes To Avoid
- Knowing and understanding that one-fifth as a fraction is equivalent to 0.2 as a decimal and that counting in steps of 0.2 is the same as counting in fifths.
3 Quick Questions (With Answers)
1. Solve this in steps: explain the method from this lesson and why each step matters.
0.1 is equal to 1/10. 0.2 is equal to 1/5.
2. Use this key word in a maths sentence and explain it clearly. 'Equivalent'
Numbers are equivalent if they have exactly the same value. Use this word when showing your method, then check your final answer is reasonable.
3. Spot and fix this common maths mistake.
Mistake: Knowing and understanding that one-fifth as a fraction is equivalent to 0.2 as a decimal and that counting in steps of 0.2 is the same as counting in fifths. Correction: Make sure that pupils have the opportunity to rehearse the fact that one-fifth is equivalent to 0.2 more frequently during the lesson and at other times when looking at fractions and decimals.
