Title: Traveling Around The Unit Circle
This lesson is intended to review the key ideas associated with trigonometric functions.The design of this lesson provides a collection of reproducible activities to be used in a classroom setting where students have varied backgrounds / experience with trigonometric functions.
Standard(s): [MA2015] ALT (9-12) 40: Choose trigonometric functions to model periodic phenomena with specified amplitude, frequency, and midline.* [F-TF5]
Title: I Can Determine The Height Of A Rocket!
The lesson is intended to give students a fun real-world experience in applying their math skills. They will use trigonometric ratios to calculate heights of tall structures. They will also use the Internet to convert their calculations from standard to metric units and visa versa.
Standard(s): [MA2015] GEO (9-12) 39: Use geometric shapes, their measures, and their properties to describe objects (e.g., modeling a tree trunk or a human torso as a cylinder).* [G-MG1]
Title: Trigonometry for Solving Problems
This lesson, from Illuminations, is comprised of three activities. Students analyze situations, check for limitations, and examine appropriate solutions using trigonometry. They also practice manipulating trigonometric functions and substituting equivalent expressions.
Standard(s): [MA2015] ALT (9-12) 39: Define the six trigonometric functions using ratios of the sides of a right triangle, coordinates on the unit circle, and the reciprocal of other functions. (Alabama)
