Use the Gooru Collection, Buy an HDTV to:

  • do Text-dependent Research into consumer reports about screen sizes and optimum viewing distances;
  • study the Proofs of the Pythagorean Theorem and practice the geometry and algebra you can use to choose the best-sized HDTV, design a viewing space, and write a convincing proposal;
  • construct a well-researched, mathematically-reasoned argument for the screen size and the design of the viewing space that you will be recommending to the purchasing committee at your school. (Formulating an Argument using Pythagoras' Theorem)

Click the "narration" bubble speech bubble in the upper-right corner of each Gooru Resource to find assignments, guides, and examples.
