The lesson today focused on how to perform rotations without a grid as reference. We went over how to use both a protractor and a ruler in order to do this. The students also saw how a rotation is actually a composition of two reflections over intersecting lines. We did 2-3 examples of these drawings together before the students got started on their assignment.
Assignment: lesson 3-3; page 126-128; #2, 4, 12, 14, 16-24 (skip #17, 23)
