I saw this idea on here and it did not work. I started tinkering with the idea this past weekend and came up with this. Thanks to Ross Chakrian for his great gifs.

Crack the Code is one of my favorite cooperative activities. While there are several versions of this activity, I found the one created by Ryan Ellis particularly interesting. I discovered it while listening to his podcast . I then headed to his website to see the activity sheets he created. Inspired by this activity, I created a Google Slides doc to use in class. Click on the pic below to view a copy. Download or make a copy for yourself! The last two slides are the Teacher instructions. Enjoy!
