This bundle includes 4 resources.

Resource #1 - Printable ASTC/CAST Poster

This poster can be used multiple ways:

• Individual reference sheet for students to use while studying
• Incorporated into notes
• Printed on a larger scale up to 18x24 inches - helpful if your school has a poster maker that can print out large image files.

Resource #2 - Discovering CAST/ASTC for Trig (Exploration Activity)

This resource is a great exploration activity for Pre-Calc to introduce evaluating trig functions and a great transition to the Unit Circle. ASTC stands for All Students Take Calculus, or sometimes referred to as CAST.

It includes the following:

• Discovery activity where students plot the "same" coordinate in all 4 quadrants to write all 6 trig ratios (sin, cos, tan, csc, sec, cot).
• This can be used as a class activity, flipped classroom, independent activity after a quiz, etc.
• At the end, there is an opportunity to have a class discussion about what they discovered and you can create the ASTC poster with them.

Resource #3 - Evaluating Trig Functions Using CAST/ASTC

This resource includes notes on how to evaluate trig functions given two different scenarios. I teach this lesson directly after my students discover the CAST/ASTC method.

• Steps on how to evaluate all 6 trig functions given a coordinate.
• 2 practice problems with being given a coordinate.
• Steps on how to evaluate all 6 trig functions given a trig ratio.
• 3 practice problems with being given a trig ratio.
• 2 practice problems where students determine which quadrant to draw a triangle in given parameters.
• The practice problems also include radicals and rationalizing denominators.

Resource #4 - RRCV Notes & Practice (Evaluating Trig Functions w/o a Calc)

This resource includes notes on what RRCV is and how to use it to evaluate trig functions. The resource includes the following:

• Notes on what each step of RRCV is.
• 10 practice problems where students evaluate trig functions without the use of a calculator. They must use reference angles, the hand trick, and CAST/ASTC to evaluate trig functions.
• The practice problems include radians and degrees, as well as all 6 trig functions.

Ready to move onto the Unit Circle? Notes and practice are available, as well as other trig resources.

Enjoy!
