Instructional Ideas
- Have class members calculate the ratios of the perimeters and areas
Classroom Considerations
- Be aware the ratio of figures is not the same for the side lengths and the perimeter and area
- The measurements are to the nearest hundredth so there are some rounding errors
Pros
- Contains a link to a lesson that uses the resource
- Calculates lengths and areas in a universal measurement that does not depend on screen size
Cons
- None
