Today Andrew and I completed an activity regarding cross sections and nets of polyhedrons. The activity showed us various 3-D figures with a plane sliced through it. The questions asked us to identify what shape the cross section would make on the intersected plane. These problems were difficult yesterday, but today we started to get into a groove of being able to visualize it. We also discussed nets, which are like the unraveling of the surface area of a figure. We visualized figures from the top, front and sides, and compared the outlines. Andrew was really good at seeing it (better than I was, he could visualize it quicker!).
