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 double and halve 2-digit numbers. They will explore division as both grouping and sharing and learn to use times table facts to find the quotient for 2x 5x 10x tables.
Lesson Summary
You will learn to explain how a divisor of one affects the quotient.
Key Notes
- If the divisor is equal to 1, then the dividend and the quotient will be equal.
- Any number divided by 1 is equal to itself.
Vocabulary To Learn
- Dividend: The dividend is what we are dividing.
- Divisor: The divisor is what we are dividing by.
- Quotient: The quotient is the result after division has taken place.
Common Mistakes To Avoid
- Children are unsure as to why, when the divisor is equal to 1, the quotient is equal to the dividend.
3 Quick Questions (With Answers)
1. Solve this in steps: explain the method from this lesson and why each step matters.
If the divisor is equal to 1, then the dividend and the quotient will be equal. Any number divided by 1 is equal to itself.
2. Use this key word in a maths sentence and explain it clearly. 'Dividend'
The dividend is what we are dividing. Use this word when showing your method, then check your final answer is reasonable.
3. Spot and fix this common maths mistake.
Mistake: Children are unsure as to why, when the divisor is equal to 1, the quotient is equal to the dividend. Correction: Use physical resources e.g. counters or children to represent both sharing and grouping contexts to help children to visualise the idea before applying to abstract equations.
