## Reflection: Grappling with Complexity Spotting Two Dimensional Shapes - Section 3: Collaborate

I noticed that some students admired the shapes more than the attributes. Many of them were unable to compare the difference in the shapes attributes. Because students struggle with understanding that these shapes have a flat surface, I let them explore the shapes by handling them. Students seem to notice the attributes after they have had enough time to examine them on their own.
