Instructional Ideas

  • Take the class outside and conduct measurements to determine heights of actual structures
  • Provide examples without images for learners to practice drawing pictures from descriptions

Classroom Considerations

  • Pupils should understand proportionality and be able to solve proportions prior to this lesson
  • Builds on concepts developed in the previous fifteen lessons in this 36-part series

Pros

  • The lesson takes time to investigate the different proportions that are possible for the same figures
  • Concepts in the lesson demonstrate trigonometric ratios

Cons

  • None
