This is a great resource for practicing the pythagorean theorem in middle school. There are a lot of questions that students get to go through. I like the use of arrows to instruct students on the sides of the triangle. At the beginning the students are asked to see the relationship between the sides 3 different ways in hopes they see the actual relationship. What happens if they don't see the relationship after the third time? On the Google Doc, it goes to a question. I do like that you explain what the student did wrong when they answered a certain way.
Goes to Google doc outline of StAIR - wish I was able to review actual StAIR assignment.
