We started our lesson by taking down notes in our interactive foldable graphic organizer. I project the notes on the overhead screen for them to copy. I then put a printed copy of the poster on my bulletin board.

Next I gave them this sheet of triangles and quadrilaterals and they colored in each of the corners.

The next step was to prove that the interior angles of a triangle were 180 degrees and 360 degrees for a quadrilateral. The students tear of the corners of the shapes and put them together to form 180 or 360 degree combined angles, thus proving the angle sum theorem.
