Lesson

Sometimes, we need to know how to write a number sentence from a story problem.

There were $2$2 rows of trees in a field, with $3$3 trees in each row.

1. Write a number sentence for this story problem to find the total number of trees in the field.

## Learn

How do we know if we need to multiply or divide, when we have a story problem? Let's see if we can find some clues, in this video.

### Apply

A teacher wants to divide up her class of $6$6 students evenly onto $3$3 tables.

1. Write a division number sentence for this word problem.

2. How many students will there be at each table?

Remember!
• If we have a total to share, we use division to work out how many groups, or how many in each group.
• If we have a number of equally sized groups, we need to multiply to work out the total.
• Multiplication and division are opposites but you can use fact families to help you to solve questions.
