Counting in ten groups

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.

This math skill instructs on counting objects by grouping them into sets of ten. This technique simplifies the counting process by breaking down larger quantities into manageable clusters, allowing easier addition of the grouped totals.
