 * For 21st Century Educators **


 * Date: TBD (~Feb. 2011)

Period(s): Advanced Geometry **


 * Standard/Performance Indicator: Geometry and Spatial Sense 9-2: Apply proportions and right triangle trigonometric ratios to solve problems involving missing lengths and angle measures in similar figures. **


 * Instructional Objective: Students will be able to use sine, cosine and tangent to solve for missing lengths and angles in right triangles. **

**
 * Teaching Strategy: Teacher will have previously explained the three basic trigonometric and their corresponding ratios. Students will work in small groups (no more than 2 or 3). Teacher will take students to a computer lab. Each group will share a computer and scientific or graphing calculator.


 * Student Activity: Students will develop "word" (application) problems (1-2 per group), and post them on the class wiki. **


 * Materials Required: Pencils, papers, scientific or graphing calculator, and a computer with internet access. **


 * Evaluation: Students will be responsible for making sure that the problems they posted can be solved. (Making note of the correct answers on a paper to be turned into the teacher. **


 * Extension/Homework: Students will log onto the wiki, copy down and solve ALL of the problems (with 75% accuracy) that have been posted. ** ||
