xxx I am new to this forum and thought that I might as well jump right in. I began student teaching on Jan. 3rd, and I have my first observation on February 1. I wanted to teach a lesson that would coincide with our lessons in math, so I have the option of symmetry or perimeter. Which do you think would be better to do? Also, could you give me some ideas that I could do for each lesson? Or if anyone has a lesson they have done before that I could use? Thanks!
