Trailfire

Well, my experience with Trailfire had its ups and downs.  Overall I would say that I like the idea of Trailfire a lot, but it had its kinks.  A big problem that I encountered came when I made my trail on my laptop and then tried to open it in the education computer lab.  There were some things missing and the trail had some glitches.  I think that that has worked itself out, but it makes me nervous to assign Trailfire someday because students might have big problems with it. Again, I like what Trailfire tries to do, especially for work in an elementary classroom.
The first half of my trail takes you through using the trig functions. There is some solving of equations that have the trig functions in them as well as solving word problems involving right triangles. The second half of the trail is about the unit circle. It has you graph degrees and radians on a unit circle as well as solve equations using the unit circle.
