Instructional Ideas
- Have the class work in groups to create the required constructions
Classroom Considerations
- Activities require a compass and straightedge
- Lesson assumes that pupils already know how to do basic constructions (Module 1)
- The third installment of a 23-part module
Pros
- Reinforces concepts learned in previous lessons and modules
- Explorations keep learners involved in the subject material
Cons
- Lesson likely underestimates the amount of time necessary for the exercises
