Still working with triangle dilations

Well, today did not progress as far as I hoped. Students still had quite a few of the tasks from the Triangle Dilations packet. I told students to continue to work on these problems. I hoped that they could work on these for 15-20 minutes, we could then discuss responses, and then move into the next investigation set. Instead, the class worked on the problems for almost the entire period. I took time at the end of the period to have a class discussion covering the first four pages. Next class we'll wrap up the discussion and move into the next investigation tasks.
