The following lesson was created by making changes to Lesson #11(original lesson) from the OKRESA website. Lesson #11, as well as others, were developed within a collaborative project between Okefenokee RESA, Coastal Plains RESA, and Southwest Georgia RESA. These units were created in effort to provide a resource for lessons to assist teachers as they implement Mathematics I and II. The units were written by high school mathematics teachers. This revised lesson provides students with an outdoor activity in which to apply what they have learned about the right triangle trig ratios. This lesson should only be used after the student has demonstrated an understanding of the right triangle trig ratios, complementary angles, and angles of elevation/depression. In the end, the students will approximate the height of various objects such as trees, light poles, or buildings using a hypsometer and trigonometry. Note: In order to use the assessment, a teacher must have acces to the TI-Navigator system for a class set of TI-84 plus graphing calculators.
