Intro to Trigonometry / What is Similarity?
 
Big Idea: It all starts with vocabulary! The study of words and how precisely we can use them is one of the key structures introduced as this course begins.

Course Structures and the Similar Triangles Project, Part 1
 
Big Idea: There are a few tools I use that help students own their experience in this class. Today I introduce them: some explicitly and some implicitly.

Finishing Up the Similar Triangles Project
 
Big Idea: It's time for students to synthesize what they've learned about the trigonometric ratios, precision, similarity, and patterns. Today's work period gives students a chance to clarify their thinking and to put it in writing.

Solving Right Triangle Trig Problems
 
Big Idea: In this review lesson, students have the opportunity to solidify their knowledge of right triangle trigonometry by working on some of the classic problems of prior introductory trig units.

Constructing Special Triangles on Geogebra
 
Big Idea: If one's goal is to make productive use of tools, then one must spend some time playing with those tools.

Using Special Right Triangles and Spotting Some Patterns
 
Big Idea: What does it really mean to memorize something? To recognize the underlying structures and patterns, and to use them to make sense of and remember, conceptually, what is happening.
