- Lesson Plan →Objectives, pacing and practice, built from this lesson's brief.
- Guided Notes →One page your students fill in and keep.
- Exit Ticket →Three items at the end of class. No student accounts.
- Re-teach →After an exit ticket: who missed what, and what to do tomorrow.
- Homework →Assign practice; it grades itself.

What you'll learn
- Compute the circumference of a circle using C = 2pir or C = pid, choosing the form that matches the given information
- Compute the area of a circle using A = pir^2, converting from diameter to radius when necessary
- Express answers in terms of pi or as decimal approximations, as the problem requires
- Solve for a missing radius or diameter given the circumference or area of a circle
- Compute the area of shaded regions, semicircles, quarter circles, and annuli by combining circle formulas with other geometric reasoning
