Lesson details
Learning outcome
I can use the relationship between the 4 and 8 times tables to solve problems.
Key learning points
- Multiples of 8 are all multiples of 4 but not all multiples of 4 are multiples of 8
- Multiples of 8 are double the multiples of 4
- Multiples of 4 are half the multiples of 8
Keywords
Multiple - A multiple is the result of multiplying a number by another whole number.
Doubling - Doubling is the act of becoming twice as many.
Halving - Halving means to divide into two equal parts.
Common misconception
Pupils may find it difficult to solve problems or misunderstand questions.
Model clearly how to identify key phrases and words which will identify the operation and equation required for word problems. This could involve drawing bar models or other representations.
Teacher tip
By this point fluency in 4 and 8 times tables will support children in solving these problems. Continue to chorally rehearse the 4 and 8 times tables.
