Does anybody use an open source text for single variable Calculus? To elaborate, I am teaching to future elementary school teachers, and it will be inquiry based with a lot of activities that I have developed. So, I want a text that is free for the students, if it came with activities or was activity driven that would be ideal, but I do not expect to find the idea. Basically, I would like to select something that comes with a recommendation to be used as an aid.
