Modeling and Counting
Trixie was 3 years
and 4 months when this video was made.
The Problem
Suppose that you have 5 chickens and that you give 2 of them to me.
How many chickens do you have left?
What To Look For In This Video
- Trixie made a model of the problem. She counted out 5 blocks to represent her 5 chickens and then gave 2 of her "chickens" to me. She then counted the ones that she had left.
