Appendix on Implementing District Standards
G-CO 12: Make formal geometric constructions with a variety of tools and methods (compass and straightedge, string, reflective devices, paper folding, dynamic geometric software, etc.).
During this unit, students will construct many formal geometric concepts including circles with trilateration and angles and triangles with triangulation. To do so, they will use tools such as drawing and directional compasses, protractors, tape measures, and straight edges.
G-SRT 8: Use trigonometric ratios and the Pythagorean Theorem to solve right triangles in applied problems.
Students will complete a card sort and order activity. They will be given cards on which will be each step of solving the tangent ratio for distance. Students will have to put these cards in the correct order to see how the equation was manipulated to become the formula that determines the distance between themselves and a nearby landmark.
G-GMD 4: Identify the shapes of two-dimensional cross-sections of three-dimensional objects…
When determining how many satellites are necessary to geolocate someone on Earth (or in space), students will see that identifying the cross-sections between the satellite’s spherical projections and Earth will impact the number of satellites needed for GPS to work effectively.
