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
