Triangles with a product and two factors, written as four facts. Some have a missing number.
What kids practice
Division splits a total into equal groups. 12 ÷ 3 can mean sharing 12 things equally among 3 groups (4 in each), or making groups of 3 from 12 things (4 groups). Third graders learn that division is linked to multiplication. To find 12 ÷ 3, think "3 times what is 12?"
Watch for
- Sharing unequally, or leaving some things out.
- Switching the numbers, like writing 3 ÷ 12 instead of 12 ÷ 3.
- Mixing up the number of groups and the number in each group.
It's free to print, with Fewer, Standard or More on the page and an answer key. See the full division concepts guide for 3rd grade.
