"I understand nets can be useful to some people for visualizing surface area, so it's important to teach about them, but I don't understand why students are REQUIRED to use them. ( http://www.corestandards.org/Math/Content/6/G/ , 6.G.A.4 )
If you're one of those people (like me and a lot of my students) who find it easier to picture each side & add up their surface areas WITHOUT mentally unfolding into a net, would you lose anything later by not learning about nets?" --@msjwright2
