Solve problems using the relationship between 3 and 9 times table
Lesson details
Learning outcome
I can solve problems using the relationship between pairs of 3 and 9 times table facts with the same product.
Key learning points
- Multiples of 3 are also multiples of 9
- In any product in the 9 times table, there will always be three times the number of 3s as there are 9s
Keywords
Product - A product is the answer when two or more numbers are multiplied together.
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 3 and 9 times tables will support children in solving these problems. Continue to chorally rehearse the 3 and 9 times tables.
