This large set of fillable forms from The Learning Curve is a treasure chest of interactive graphic organizers that encourage creative and critical thinking skills. According to the site, “This collection of thinking strategies and tools have been created and inspired from Mick Walsh’s experiences using the Thinking Curriculum, CoRT Thinking, Tribes Program and Visible Thinking from Harvard University.” Included on this list are pages for Six Thinking Hats and P.M.I. However, there are many other intriguing ones that I have never seen anywhere else, such as Time Machine and Truth Traffic Lights. For some new ideas on how to engage your students in deep thinking, I highly recommend Thinking Tools.
