Modeling - Hard Subtraction 1
Trixie was 3 years
and 9 months when this video was made.
The Problem
I have 2 parts of a snake. You have 6 parts of a snake.
Who has more parts of a snake - your or me? How many more do
you have than I have?
What To Look For In This Video
- Trixie made a model of the problem. She represented the parts of a snake with stones from her garden. She gave me 2 stones, gave herself 6 stones, matched 2 of her stones with my 2 stones, and then counted her unmatched stones.
