2.+Rationale+and+Relationship+to+Standards

=Rationale and Relationship to Standards= Active learning is a great way to get students interested in and excited about mathematics. Active learning is a particularly useful pedagogy for students to build conceptual understanding.

Learning Target: Students will understand the relationship between similar triangles and trigonometric ratios.

The Common Core Standard this addresses is: G-SRT.6 "Understand that by similarity, side ratios in right triangles are properties of the angles in the triangle, leading to definitions of trigonometric ratios for acute angles."

This particular concept is critical for students to understand what trigonometric functions are actually representing and why they work. When students continue into trigonometry and calculus, they often think that trigonometric functions are mysterious and lack real world meaning, having this concrete example will help them build knowledge as they move into graphing sinusoidal functions by thinking about what side length ratios are at different angles.
