Master Teacher lessons
Big Idea:
Students get to build the graph of sine or cosine with yarn and spaghetti.
Big Idea:
Radian rotation-style review of radians and radian measurement.
Big Idea:
How is the unit circle related to "triangle measurement"? A story of two equivalent definitions.
Big Idea:
You are riding a Ferris wheel near the Golden Gate Bridge. When will you be high enough to see the full view? Students attempt to answer this question using some knowledge of right triangles.
Big Idea:
The unit circle allows us to extend the trigonometric functions beyond the confines of a right triangle.
Big Idea:
You are sitting on a Ferris wheel. Who is directly across from you? Below you? Diagonally across from you? Use a representation of the unit circle to make generalizations.
Big Idea:
Why do these trig equations have so many solutions?
Big Idea:
Why do we use a unit circle? How can we use it to represent all angles for all circles?
Big Idea:
Why should we divide the circle into 360 parts? Isn't there a more natural unit? Yes - the radius!
Big Idea:
Students work on midterm review and let you know what they still need help with.
Big Idea:
Why do we use a unit circle? How can we use it to represent all angles for all circles?
Big Idea:
Students will turn a locker combination into a secret math code (angles).
Big Idea:
How do I even start this problem?! Give your students tools to help make sense of and work with trig problems.
Big Idea:
Students will review and extend their knowledge of trigonometric ratios.
Big Idea:
Radians are radical! Use them to make working with trig ratios easier.
