The edge of a surface is the line separating two of its surfaces. A flat surface makes up the face of a three-dimensional shape. Among these qualities are faces, edges, and corners. There are characteristics shared by all three-dimensional shapes. They are all objects that we can hold, such as a pencil, phone, table, boxes, ball, etc. ( 2 ) Make sure that all the sides fit together properly by picturing how the net will be folded to create the solid.Īs a recall, three-dimensional (3D) shapes take up space. ( 1 ) Make sure that both the solid and the net have the same number of faces and that the solid’s faces correspond to the same faces in the net in terms of shape. These are the conditions to be met if a net forms a solid or a three-dimensional shape: A geometric net pattern is produced when the surface of a three-dimensional figure is spread out flat, and each face is visible. What are Geometric Nets? DefinitionĪ geometric net refers to a two-dimensional shape that can be modified to create a solid or a three-dimensional shape. In this article, we will define geometric nets, learn various net shapes, determine whether a net constitutes a solid, and calculate the surface area and volume of a shape from the perspective of its geometric net. The vital spatial skills you acquire from a foundational understanding of form nets can thus develop further into other more challenging design applications.

Engineers and developers use powerful and advanced computer-aided design (CAD) software to assist in their work. Understanding how a three-dimensional shape is constructed from two-dimensional parts is important for every aspect of three-dimensional design, not just when building boxes. This is just an immediate example of the use of geometric nets, but it offers other important applications. Let us say, for instance, a flat corrugated paper box will be in its three-dimensional shape upon folding up its 2D net. These solid shapes’ ability to be represented in two dimensions by a shaped net is useful, especially in getting its surface area. Three-dimensional (3D) objects have several flat surfaces (faces) made of polygons that are connected by edges and corners (vertices).

Learning ideas for foldable 3D shapes: You can also use tape if that’s easier for you (or you don’t have glue). This will help make sure it stays together. I suggest adding a few dabs of glue to each tab and then hold it in place for a few seconds before gluing the next tab. Then, carefully fold each tab so that it can be used to glue the shape together, and fold each side of the shape.įinally, glue each side together. This will help them see and learn math vocabulary. If your students are older, have them label the different parts of the shape (face, edge, base) before assembling to use as a reference throughout their study of shapes! 🙂 If you’ve printed on white card stock as I have, take some time to get creative and color or decorate the shapes before assembling them! This could make a great math art project! I have tried it both ways, and regular paper is just too flimsy.Īfter printing, simply cut out the 3d shape nets on the solid lines. I highly recommend printing the nets on stock paper rather than regular paper.
