I’ve found it useful to give junior PreCalc H students time to work together on take home “exams” in class because it builds some fantastic community and teamwork skills. I instituted new rules to their work: Non-permanent work only. If they work on paper, it has to be tossed. No pictures either.
My thought process is that when they go away to write up the problems that they worked on together, there will be some good things going on in their brains to try and rethink the (upwards of) 20 moves that had to be made to solve these problems (IB questions). What do you think? Does this idea have any basis?
This activity also stands in nicely for a trig review thing that I used to do quite differently.
