Standards Addressed:
MGSE.9-12.G.GPE.1 Derive the equation of a circle given center and radius using the Pythagorean Theorem; complete the square to find the center and radius of circle given by an equation.

Learning Targets /Success Criteria:
LT: I can identify parts of a circle from the equation written in standard form.
SC:
• I can identify the center of the circle by taking the opposite of h,k.
• I can identify the radius of the circle by taking the square root of the constant.
LT: I can use the graph of a circle to write the equation of the circle.
SC:
• I can find the coordinates of the center.
• I can determine the length of the radius.
• I can use the center and the radius to write the equation in standard form.
LT: I can graph a circle on the coordinate plane.
SC:
• I can identify and plot the center.
• I can identify and use the radius to plot 4 additional points.

Introduction/Connection (Activator): Equation of a Circle g/o (attached below as Equations of Circles Notes). Students will attempt to complete cloze notes based on info given in diagram.

Direct Instruction/Guided Practice:
--review bellringer introducing standard form of the equation of a circle.
--guide students in graphic organizer Graphing Circles Graphic organizer (attached below). Guide students in how to find the center of the circle and the radius and how to use this information to graph a circle.
--guide students in completing selected problems on Graphing circles and writing equations hw 2 (attached below).


Independent Practice/Differentiation/Collaboration:
--differentiation: cloze notes, graphic organizers, foldables (if used), partner work (if used), accelerate/challenge problems for certain learners, additional/guided one on one support for struggling learners
--independent practice: students will complete Graphing Circles practice w/s (attached below).

Summarizer/CFU: TOTD

Assignment: TBD.
