Students will learn the standard form of the equation of a circle. They will complete the square to find the center of the circle and radius. A link to a Geogebra exploration is also included.
A worksheet and key is provided. Students are asked to graph circles, write the standard form given the center and radius, write the equation given the center and a point, and write the equation by completing the square.
Doodle notes are an effective way to activate the creative side of the brain. Students spend less time copying notes and more time engaging with them.
