Common Core Secondary Math brings you “Fluent in Math: Fluency Checks for the Common Core” . The Common Core State Standards in Math (CCSSM) stress fluency with skills and procedures along with conceptual understanding and mathematical applications.
Fluency with mathematics at the secondary level requires the same repeated practice and feedback as multiplication facts did in elementary school, however, generating the required fluency checks takes time. Many middle and high school students still believe that as soon as you take a math test, you can purge the information from your brain. I created these fluency checks because I and my students needed them and I hope they can help you and your students.
HSF.TF.A.2: Explain how the unit circle in the coordinate plane enables the extension of trigonometric functions to all real numbers, interpreted as radian measures of angles traversed counterclockwise around the unit circle.
HSF.TF.A.3: Use special triangles to determine geometrically the values of sine, cosine, and tangent for pi/3, pi/4, and pi/6, and use the unit circle to express the values of sine, cosines, and tangent for pi-x, pi+x, and 2pi-x in terms of their values for x, where x is any real number.
You will receive:
• Four “No-Prep” Unit Circle Trig Values Fluency Checks formatted two per page. Simply copy & cut in half.
• Covers all six trig functions for values between 0 and 360 both positive and negative.
• Answer Keys for all versions
• The numbers and powers are simple enough that no calculator is needed.
• The questions in each quiz follow this format:
o 6 questions, 1 per ratio in degrees
o 6 questions, 1 per ratio in fractional (pi) radians
• Suggestions for use depending on the course.
