My goal with quests is to provide students an opportunity to learn outside the math curriculum. I believe Classcraft should be optional and because of that, I cannot use quests as my math assignments (even though that would be cool). Instead, I'm working on quests where students watch videos, listen to podcasts, etc. and submit a 1-2 paragraph response. This could be used in any subject area for high school and possibly even junior high students. I just finished a 13-quest TED Talk quest line and am currently working on one for TheMathDude podcast. Here's my TED Talk quest line and I'll post my TheMathDude one when it's finished!
