CCSS: 6.G, 7.G, 8.G.6 - Explain a proof of the Pythagorean theorem

Students can engage in several of the math standards of practice: MP3 - construct viable arguments and critique the reasoning of others, MP4 - model with mathematics, MP7 - look for and make use of structure, and MP8 - look for and express regularity in repeated reasoning. Students can also engage in practice MP5 - use appropriate tools strategically by using a program such as Geometers Sketchpad or Geogebra to investigate the theorem.

Here is a GeogebraTube app on the Pythagorean Theorem  Simply click on and drag points A, B or C to manipulate the model.
