This lesson focuses on G-CO.C.11: developing properties of rectangles, using those properties, and proving theorems about special parallelograms (rectangles). Students explore concepts of parallelograms and prove theorems in groups.  Core Action 3 is strongly exhibited in this lesson. 

This video was annotated using this version of the Instructional Practice Guide (IPG). A current version of the IPG is available here.
