So unlike the description on the instructions I found my child did not have a big math test. Nope this was a case of a homeschool Mom ready to do a unit on triangles and totally forgot about protractors.
Google to the rescue. I found a few resources. I went with ehow The instructions were easy and simple and became a small project. However I suggest you use this picture. Just realized it failed to add before.
I really like the idea on wikihow.
However I do not have any more of the self adhesive vinyl from the dollar store.
