Overview: Students time themselves building squares and cubes. Then predict the effect on time needed to build the squares and cubes if the side length is increased.
Curriculum Expectations
- Number sense and algebra: Solve problems involving proportional reasoning
- Measurement and geometry: Solve problems involving the measurements of two-dimensional shapes and the volumes of three-dimensional figures
Learning Goal:
- If the side length of a square doubles the area is four times larger.
- If the side length of a cube doubles the volume is eight times larger.
- The time it takes to build a square or cube will be proportional to its area or volume
