Introduction:

Prior knowledge would be special right triangles and already discussed where the values in quadrants of unit circle come from...

Group Size: Whole class

Learning Objectives:

Plan for students to learn(memorize before we can apply) the unit circle

Materials:

paper with tick marks at each special angle & axis of unit circle

Procedures:

Day 1

have students create an unit circle card Front: radian, degree, coordinates and Back: just circle with special angles marked

use that card while being verbally/tactilly prompted for values

Day 2

Students will be given a blank unit circle at start & end of class and asked to write down all angles in degrees and radians

TIMED assessment used as a benchmark for growth not a grade. Graded by student & collected.

Assessment:

Day 3

Students will be given a blank unit circle at start & end of class and asked to write down all angles in radians and coordinates of special angles including axis.

TIMED assessment used as a benchmark for growth not a grade. Graded by student & compared to yesterday's attempt and collected.

Answer Key or Rubric:

Students will be given a blank unit circle and asked to write down all information about each special angle including axis: radian, degree measure & (cosine, sine) in coordinate form

I give my students 4 minutes for the entire circle and it is out of 66 points.
