### Author: Kenneth Vos

This module is a basic introduction to the global positioning system. Mathematics includes basic distance relationships, angles, solid geometry relationships such as intersecting spheres, and latitude & longitude. Applications areas considered include trucking, agriculture, and recreation.

**TechMAP**

Covering topics from Algebra I to Precalculus, TechMAP modules show high school students real, immediate uses for mathematics.

**All students MUST PASS the same standardized tests in order to graduate and succeed. All 22 TechMAP modules show tangible, real-world applications of the material on these exams, driving home required math skills.**

**The mathematics required by state tests is taught in algebra and geometry courses, but for many students this is not enough. TechMAP modules demonstrate these skills in vocational fields; they help reinforce existing mathematics courses through actual career activities. These modules are self-contained with exercises, teacher notes, handouts, etc., and can be used individually or together. Each module takes one to three weeks of classroom time.**
