![]() The 3d shapes set pictured below is available in my shop. These 3-d geometric shapes would be fun hanging up by a string as a decoration, too! To fold this up, you just start folding the triangles and it sort of just bends into the shape. You could probably fit a 2.5 inch one on a paper. The 3d octahedron I made 2 inches per side, but it ended up very small. Six of them are in a row facing opposite directions The other two are hanging off the ends. It is a series of 8 equilateral triangles. How to Make a 3d Octahedron: The octahedron was the trickiest. I made this by cutting into the other parts and removing the sections. Then one of the sections needs a square cut-out. How to Make a 3d Cuboid: For the cuboid, I divided the paper into fourths. Paper Models for Download NETS - Polyhedra & Others Welcome to Math Salamanders Paper Models for Download, including nets for polyhedra and other models. You have to make sure each side of the triangle is equal to the sides of the square. How to Make a 3d Square Based Pyramid: A Square-based Pyramid is started with a square and then triangles coming out from each side. It ended up being 2 3/4 of an inch per side. I measured the sides of my paper sections to make the triangle side the same length. How to Make a 3d Triangular Prism: The Triangular Prism is made by dividing the paper into thirds. Then in the center section you will make your triangular cut-outs. You need four squares going down and three going across. How to Make a 3d Cube: For the 3d cube, you need a cross-like shape with even squares.

Nets (templates) and pictures of the paper octahedron. The model is made of 8 equilateral triangular faces. How to Make a 3d Cone: For the cone, I traced a large circle, then cut a wedge out of the circle. The octahedron is one of the 5 Platonic Solids (convex regular polyhedra). To make each of these 3d shapes I used an 8 1/2 x 11 sheet of paper to make them. There are 6 common 3d shapes that I am going to teach you about today. I also have printable templates with a few more 3D geometric shapes, if you want a simpler way to make them! They are available in my shop. They were pretty fascinated by it all.Īll you need to make these paper 3d shapes is paper, scissors, a pencil, a ruler and tape. Then they tried making lots of other kinds of shapes out of paper. They played around with them for a while. Learning to makes these shapes would be great for geometry or just to practice the 3d shapes names. ![]() Plus I also have printable templates available for you. Today I want to share with you how we made 6 different 3D shapes out of paper. I think it is so neat that from just a piece of paper you can make so many different things. I have always been fascinated with origami and other paper folding crafts. If anyone has photos of some models they have done, just let us know, and we can feature them here.Let’s make 3d Shapes with paper! It’s easier than you may think. If you use cardboard boxes, then it might look better if you paint the inside and show that on the outside of the model.įinally you can color in each side in fashionable colors, or you could glue on pictures or designs from magazines, and you could even attach string and make a mobile! You can use good quality cardboard for the job, or just cut up some cardboard boxes from the kitchen (ask first!). ![]() Rubber bands (not too tight!) can help hold the model together while the glue dries. This means to carefully scratch along the line with a knife, nail or similar object (use a ruler to keep the line straight), just don't cut through! To make folding easier and the final product more professional-looking, you can score along the lines before folding. If you print on normal paper you could then glue them onto a sheet of cardboard, or just use the paper template as a guide for cutting the cardboard.Īfter cutting out the shapes you need to fold neatly along the dashed lines. It is best to print these model templates on cardboard or thick paper (160-210 gsm), but they can also be printed on normal paper, they just may be a bit "floppy".
