I am teaching Trigonometry as an active learning class.  Students have activities where they discover and develop the concepts for the course. I've created these activities to enable students to work in groups and share with their peers or we sometimes work together as a class and discuss them.  I've created all of the activities, while some of my colleagues have created the projects (these are noted below).

I have editable originals if you are interested in taking what I've done and tweaking it to fit your needs/style.  Simply send me an email and request those.
