Instructional Ideas

  • Use straws cut to specific lengths and have the class build triangles to determine which ones are right triangles and which ones are not
  • Lead an exploration where the class finds some of the basic pythagorean triples

Classroom Considerations

  • For New York, the standards are labeled as post-test standards; that may not be true for all areas
  • 15th segment of a 16-part unit

Pros

  • Resource encourages the use of calculators so calculations do not interfere with the lesson
  • Some of the problems have individuals analyze someone else's work — a great peer review tool

Cons

  • None
