Unit Summary
In this unit pupils will divide a 2-digit and a 3-digit number by a single-digit number using partitioning and representations and divide a 2-digit number by a single-digit number by using short division.
Lesson Summary
You will learn to divide a 2-digit by a 1-digit number using partitioning and representations (no remainders).
Key Notes
- Skip counting in steps of the divisor can be used to divide 2-digit numbers.
- Dividends can be partitioned into multiples of the divisor to divide efficiently.
- Unitising language is used to describe the process of division.
Vocabulary To Learn
- Dividend: The amount that you want to divide up.
- Divisor: The number you divide by.
- Partial quotient: Part of an answer to a division equation.
- Partition: Splitting an object or value into smaller parts.
- Quotient: The result after division has taken place.
Common Mistakes To Avoid
- Some children may continue to share one by one when dividing.
3 Quick Questions (With Answers)
1. Solve this in steps: explain the method from this lesson and why each step matters.
Skip counting in steps of the divisor can be used to divide 2-digit numbers. Dividends can be partitioned into multiples of the divisor to divide efficiently.
2. Use this key word in a maths sentence and explain it clearly. 'Dividend'
The amount that you want to divide up. Use this word when showing your method, then check your final answer is reasonable.
3. Spot and fix this common maths mistake.
Mistake: Some children may continue to share one by one when dividing. Correction: Encourage children to skip count in the divisor and remind children that it is an efficient way of dividing.
