Geometry: Polygons

I am a high school math teacher in the state of Texas. We use the CSCOPE curriculum and I am in Unit 7. I count the Unit pocket as page one.
Now on my page two-Polygons:
1. Fold the paper in half (short fold) and then unfold.
2. Fold the edges in to the center creating the shutter fold, then unfold.
3. Take the right side and fold three times to the left, then finish by taking the left and fold once to the right.

Now after spending the day at a local symposium I have heard some differing opinions on polygons. For example the one on the cover with two intersecting sides. I have come across what is called a complex polygon in my research, but have had several colleagues disagree. Please share your thoughts.
