SLT Circles 1: I understand the derivation for the equation of a circle on the coordinate plane.
Today: Let’s Jump Back In!
 Get a laptop.
 Open up Geogebra and get the Circles Applet running again.
 Finish the Manipulating Circles on Geogebra handout. This is due by the end of class.

To really prove that you’ve mastered this learning target, try these problems: Geogebra Circles Problem Solving
At the end of class you’ll have a quiz on graphing circles (without computers).
Reminder: Problem Set #7 was due yesterday.
