![]() ![]() Ultimately, with just those three constructions you could ask them to come up with a way to construct other angles, such as:ġ20 degrees (two adjacent 60 degree angles)ĩ0 degrees (a 30 degree angle adjacent to a 60 degree angle)Ĥ5 degree angle (bisect a 30 degree angle to get 15 degrees and put it adjacent to a 30 degree angle).Īlso note, the last two can also be achieved using the perpendicular bisector construction.Įdit: After all that, if possible, you may want to show them some clever constructions, like this animation constructing a regular heptadecagon (17-gon) or maybe some examples from this page. Targeted Implementation and Planning Supports This website provides a series of lessons for Ontario Curriculum topics in grades 7 through 10. Then, you could help the students discover how to do those constructions using sketchpad. Add comments to others who have posted.ĭiscuss your possible lesson ideas to incorporate Geometer's SketchPad.My suggestion would be to start with a compass & straightedge and do a few basic constructions, such as constructing an equilateral triangle(60 degree angles), angle bisectors, and duplicating angles. ![]() Review and complete as much of the following activity packet( File:GSActivity for Geometer's SketchPad.pdf) using Geometer's SketchPad you feel necessary to become acquainted to the program.Īdd any questions/concerns/thoughts on how to use Geometer's SketchPad to the following discussion board. Pros: Tutorials are excellent for reviewing concepts and assessing knowledge either before or after an in-class lesson. Please fill in the following graphic organizer to keep track of any questions/concerns/comments you have before/during/after your venture through Geometer's SketchPad.
