Checking and securing understanding of multiplication and division
Maths•Key Stage 3•Arithmetic procedures with integers and decimals
Lesson Description
I can use the mathematical structures that underpin multiplication and division of positive integers.
Lesson Overview
Key learning points
- Multiplication can be made easier by considering factors.
- Division can be made easier by considering equivalent calculations.
- It can help to think of a context when doing a calculation.
Keywords
- Partitioning
- Partitioning is the act of splitting an object or value down into smaller parts.
- Dividend
- The dividend is what we are dividing.
- Divisor
- The divisor is what we are dividing by.
Common mistakes
20 × 50 = 100, they partition the 2 and 5 to give 10 but count the zero as one of the 2 zeroes.
Make sure that partitions are written out fully. E.g. 20 × 50 = 2 × 5 × 10 × 10 = 10 × 100 = 1000
