Many solids are enclosed by flat faces: cut a solid along some faces and lay it flat to get its net; fold the net back and the solid returns. A cube's net is 6 squares (with several possible layouts), a cylinder's net is a rectangle plus two equal circles, and a cone's net is a sector plus a circle. Unfold, fold, and guess.
Meet the cube, cylinder, and cone with their flat nets: tap Unfold/Fold to watch the faces spread out and close up, then play the net-guessing quiz to build the connection between solids and flat patterns.
