This a great resource. Middle schoolers will love that they can work individually, working as quickly or as slowly as they need to go. The questions are great and the visuals really help the students understand the pythagorean theorem. Great job making the visuals so eye-catching. It should keep their attention, at least long enough for them to answer the questions. Great resource!
Just download the document (which you will probably want to do anyways), and then use the Slide Show mode for the students.
