Teachers’ Guide to Cranky Uncle
The Teachers’ Guide to Cranky Uncle offers background information and classroom activity ideas for educators interested in using the Cranky Uncle game to teach critical thinking in their classes.

One of the activities in the Teachers’ Guide is the Please Don’t Fail Me assignment, designed by Melanie Trecek-King from Thinking is Power. Melanie has also written a blog post going into greater detail into this assignment and how students responded.


Group Code for Classrooms
Teachers can sign up for a group code making it quick and easy for students to anonymously enter the game (avoiding the need to enter an email to play the game). So far, teachers have signed up from 37 U.S. states and 16 other countries.
