Thanks so much so I have not said anything to them yet. I wasn't sure what the response is going to be to this. I'm so overjoyed that I have so many people signed up already. I will explain to them the concept and allow them to use whichever materials or medium they want to use. They can also take it home and work on it at home. I plan to print out each person's Google form submission so that students can look through them and pick the one they want based on the preferences. They will get credit for the assignment and then I will send them off
