This is a lesson that would be used for review Congruence of Triangles. The students will watch a video to remind them the theorems used and then must brainstorm in a quick write to remember them all. After that they will practice drawing triangles and find their partner who has a congruent triangle, using drawing and illustrating. Another activity they will do that uses illustration is a pipe cleaner activity that will further show how to prove triangle congruence.



I also found some Web 2.0 tools that would help further this lesson.

GeoGebra This is a great tool to use for Geometry lessons. It took me a little while to figure out how to use it all but once you play around with it, it wasn't difficult to use. I used it to do an activity similar to the pipe cleaner activity in my lesson above. Students would be give triangle measurements, which they would draw on GeoGebra, After they would have prove each of the theorems, for example ASA, which I did in the screen shots below. The students could take a combination of angle-side-angle and they would show that the other measurements were the same also. It is quite similar to the hands on activity in the lesson, but this gives students another way of seeing it.

[|Bubblus] This site is used to map ideas and make brainstorming charts. Students can make their own account and can save their brainstorming. This could be another resource for students to keep their work in a place other than their notes.
