Lesson

Are you ready?

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 $10$10 trees in each row.

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

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 $10$10 students evenly onto $5$5 tables.

  1. Write a number sentence for this story 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.

Outcomes

3.OA.A.3

Multiply and divide within 100 to solve contextual problems, with the unknown in any positions, in situations involving equal groups, arrays/area, and measurement quantities using strategies based on place value, the properties of operations, and the relationship between multiplication and division (e.g., contexts including computations such as 3 x ? = 24, 6 x 16 = ?,
