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 solve problems using 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
Vocabulary To Learn
- Equivalent: Numbers are equivalent if they have exactly the same value.
Common Mistakes To Avoid
- Pupils may not appreciate that equivalent fractions and equivalent fractions and decimals have exactly the same value and can be substituted which may be beneficial when solving problems.
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: Pupils may not appreciate that equivalent fractions and equivalent fractions and decimals have exactly the same value and can be substituted which may be beneficial when solving problems. Correction: Model the thinking when there is a mixture of fractions and decimal representations in a problem and identify the decision as to whether to convert all to decimals or all to fractions as a step in the the problem solving process.
