Video Transcript

Which addition sentence is equal to seven plus nine?

To help us calculate the answer, first we need to make 10. In this ten frame, there are seven bricks. If we add three more, it will make 10.

We need to take three green bricks and add them to the seven red bricks. We added three bricks to the seven bricks to make 10, and we took three bricks from the nine to make six.

Seven plus three plus six is equal to seven plus nine.
