Teaching Transcript

🎙️

Let's use ten groups to count the number of pink triangles we have.

Notice that the groups are exactly ten each, so we have ten in the first group, and another ten in the second group.

The third group has one row of 5, and one more, which is 6

So we have ten, another ten which is 20, and then another 6 which is 26.
