Lesson details
Key learning points
- Numbers in the 9 times table are also in the 3 times table.
- When there are 3 groups of 3, there is 1 group of 9
- Multiples of 9 are all multiples of 3 but not all multiples of 3 are multiples of 9
Keywords
Multiple - A multiple is the result of multiplying a number by another whole number.
Common misconception
Lack of fluency in the 3s and 9s times tables can lead to pupils being slower to grasp the generalisation about the relationship between the 3 and 9 times tables.
Use arrays and other representations to draw clear comparisons. Multiplication grids could also be provided while pupils become more fluent in recall.
