Unit Summary
In this unit pupils will explain how to write a fraction in its simplest form when solving addition and subtraction problems.
Lesson Summary
You will learn to explain how to write a fraction in its simplest form.
Key Notes
- A fraction in its simplest form is equivalent to the original fraction.
- Equivalent fractions have the same value.
- To simplify fractions you divide the numerator and denominator by a common factor.
Vocabulary To Learn
- Equivalent: If two numbers or expressions have the same value, they are said to be equivalent.
- Common factor: When we compare lists of factors of two or more numbers, any factors that are the same are common factors.
Common Mistakes To Avoid
- Pupils think that converting a fraction to its simplest form is the same as making the fraction smaller or making the numerator have a value of one.
3 Quick Questions (With Answers)
1. Solve this in steps: explain the method from this lesson and why each step matters.
A fraction in its simplest form is equivalent to the original fraction. Equivalent fractions have the same value.
2. Use this key word in a maths sentence and explain it clearly. 'Equivalent'
If two numbers or expressions have the same value, they are said to be equivalent. Use this word when showing your method, then check your final answer is reasonable.
3. Spot and fix this common maths mistake.
Mistake: Pupils think that converting a fraction to its simplest form is the same as making the fraction smaller or making the numerator have a value of one. Correction: Ensure pupils realise that the numerator and denominator are both scaled to find a different representation of the same sized fraction. Provide examples of fractions where the simplest form does not have a numerator of one.
