- Using a protractor is a still HUGE hurdle. It really shouldn't be, but results were off by over 100 degrees in some cases.
- Allowing any shape seems like it makes the task easier, but students had no idea how to measure a reflex angle, which most likely contributed to our error problem.
- In the future, I might direct students to round measurements to the nearest 5 degrees in the hopes that it will help.
In the end they all seemed to think it was easy, which is usually a sign that something went terribly wrong.
