### 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.
