Relationships between two and three dimensional figures

In this book students will learn:

What is meant by the net of a solid
Nets of the following solids: cube, rectangular prism or cuboid, triangular prisms, pyramids, cylinders and cones.
How to use nets to find surface area?

A geometry net is a 2-dimensional shape that can be folded to form a 3-dimensional shape or a solid. Or a net is a pattern made when the surface of a three-dimensional figure is laid out flat showing each face of the figure. A solid may have different nets. Below are the steps to determine whether a net forms a solid: 1. Make sure that the solid and the net have the same number of faces and that the shapes of the faces of the solid match the shapes of the corresponding faces in the net. 2. Visualize how the net is to be folded to form the solid and make sure that all the sides fit together properly. Nets are helpful when we need to find the surface area of the solids. The book focuses on the following 7th grade math common core standards: CCSS.MATH.CONTENT.7.G.A.3 Describe the two-dimensional figures that result from slicing three-dimensional figures, as in plane sections of right rectangular prisms and right rectangular pyramids.
