12Dear Teacher,
Instead of giving students the unit circle to memorize, it’ll be more meaningful for your students to see
how the unit circle comes about and why the coordinates are what they are. This project is meant to
help students in both remembering the unit circle and understanding it. There are 2 worksheets
included in this project: Unit Circle Project Background Information and The Unit Circle. The first can be
done whole class as a way to introduce the lesson/project. The second can be done as part of the
project or you can even use it as a quiz after students complete the project.
Give each student a Unit Circle Project Directions worksheet. I assign this project independently. It’s
quite easy to grade with a checklist since it’s out of 10 possible points so you can easily convert to a
percent and assign a letter grade. Ask students to attach the rubric to the back of the project for your
convenience. You can even ask them to grade each other’s work.
Unit Circle Project Grading Rubric
The main unit circle covers most of the poster board.
The unit circle has angle measures in degrees.
The unit circle has angle measures in radians.
The unit circle has the coordinates at each point.
The unit circle angle measurements are accurate (i.e., the amount of space from 30 degrees to
45 degrees should be less than the amount of space from 60 degrees to 90 degrees).
The student drew 5 separate circles to show derivations.
All derivations were drawn by dropping perpendicular lines towards the x-axis.
The student has identified each triangle as either a 45-45-90 or 30-60-90.
