Looking for Feedback - Radical Roots

I'm looking for a bit of feedback on an investigation. I am teaching an algebra heavy geometry course, we just tackled right angle trig. The kids have seen Pythagorean theorem and such... I need to teach radicals and exponents at some point and this seemed like a reasonable time with areas of polygons and coordinate geometry around the corner.

The objectives of the investigation is for students to:
  • Develop geometrical meaning of square roots 
  • Develop geometrical meaning for equivalent radical expressions such as:
I must admit most of what is posted is not my idea, but an adaptation of content from Math Alive! Course III.

Link to the Google doc investigation.

Any and all feedback is welcome.
