TeacherKristin Andreason
Subject AreaGeometry Honors
Grade Level8
Week #April 22-26
Unit of InstructionUnit 8: Circles with and without Coordinates
Standard(s) Taught

MAFS.912.G-GPE.1.1:  Derive the equation of a circle of given center and radius using the Pythagorean Theorem; complete the square to find the center and radius of a circle given by an equation.

Learning Targets and Learning Criteria
  • identify the center and radius of a circle given its equation.
  • draw a right triangle with a horizontal leg, a vertical leg, and the radius of a circle as its hypotenuse
  • write the equation of a circle by using the distance formula (Pythagorean Theorem), the coordinates of a circle’s center, and the circle’s radius.
  • rewrite an equation of a circle in general (quadratic) form to standard form by completing the square.
Classroom Activities


  • Students will do an activity called “Build Understanding for the Equation of a Circle.”
  • Students will do Math Nation:  Section 12, Topic 5


  • Students will do problems from the Workbook on circle theorems related to tangents and secants.


  • Students will learn how to convert from the general equation of a circle to the standard form of a circle by completing the square.
  • We will review for the test by doing quizlet live.
Assignments Due
  • Workbook problems are due by April 26.
