Step 1. Collect Feedback
Both you and your students have invested a lot of time and energy into this project. Don't lose out on the valuable opportunity to gather constructive feedback from them so that you can edit and reuse your hard work! Design a survey or some other way for participants to let you know which aspects they liked and didn't like, but don't just focus on the fun! Be sure to include important logistical questions such as how long the spent, how much difficulty they had finding codes and doing activities, etc.
