Area by Counting Squares
Distinguishing between the boundary of a shape and the space it covers by counting square units.
Key Questions
- Justify why we use square units to measure area instead of linear units.
- Compare the area of two different shapes by counting squares.
- Predict the area of an irregular shape by estimating full and half squares.
