This is an assignable version of the digital applet that goes with Grade 7, Unit 3, Lesson 8: Relating Area to Circumference.
Assign this activity to students so they consider a different way to cut and reassemble a circle into something resembling a polygon in order to calculate its area.
Students using the applet should still note their responses to each question on paper so that they can fully participate in the activity and lesson synthesis discussions.
Original applet created in GeoGebra by timteachesmath.
