Intro to Trigonometry
After being introduced to the basic trigonometry functions, students calculate the height of school landmarks. They experiment with different angles to find the correct height.
Curated OER
Cartesian Coordinate System
Young scholars explore the Cartesian coordinate plane and plot points on the graph. They interpret coordinates for a point from the graph and give the ratio of rise over run for slope.
