Lesson details
Key learning points
- In a multiple of nine, there are three times as many threes as nines.
- 1 group of 9 is equal to 3 groups of 3
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.
Model using arrays and other representations. Pupils who may struggle to triple / find one third of a number may require more time to work through calculations. Multiplication grids could also be provided while pupils become more fluent in recall.
By this point fluency in 3 and 9 times tables will support children in solving these problems. Continue to chorally rehearse the 3 and 9 times tables.
