Print out the mock-up of the icosahedron on a sheet of paper, then cut it into a dotted line. This is necessary in order to leave a free space for gluing together the pieces of the figure with each other. Try to cut out the icosahedron as slowly as possible, otherwise with a slight shift your work will eventually look ugly. The need for a very accurate cut is due to the fact that all triangles in the regular icosahedron have the same sides. Therefore, if any side becomes different in length, the resulting discrepancy in size will be noticeable. Making an icosahedron from paper is a fascinating process that requires patience, thoughtfulness and a lot of paper. But the result will be for a long time to please the eye.

A paper icosahedron can be given as an educational toy to a child who has reached the age of three. Playing with this geometric figure, the kid will develop not only spatial skills and imaginative thinking, but will also become better acquainted with the world of geometry. For an adult, the creative process of constructing a paper icosahedron will allow us to pass the time, and also to surprise our relatives with the ability to make complex figures.
Such wonderful geometric bodies can be made of paper or cardboard! To do this you only need scissors, glue and, in fact, paper. Below are suggested schemes for creating these bodies. Simply transfer them to a sheet and cut them out. Then glue in the places of gluing. Such geometric volumetric bodies are not only very pleasing to the child. Created with their own hands with him, they will give an opportunity to acquaint the child with the volume and projection.
You will be able to demonstrate how several ordinary triangles turn into a pyramid. Or how the squares become a cube. Ask the child to guess which figure will come from a certain sweep, and then glue it. It perfectly develops spatial thinking!
6 4 Here are some schemes by which you can make three-dimensional geometric shapes. The simplest is a tetrahedron. Harder it will be to make an octahedron. But this voluminous figure is a dodecahedron. One more is an icosahedron.
More details on the production of three-dimensional figures can be found here. This is how the three-dimensional figures look like they are not assembled: And now they look ready: Of the voluminous geometric figures, you can make many original hand-made articles, including gift wrapping.
The system chose this answer as the best 7 For children to better remember what kind of geometric figures are, and they knew how they are called, you can make three-dimensional geometric figures from thick paper or cardboard. By the way, on the basis of them you can make a beautiful gift wrapping. You will need: • thick paper, or cardboard (better color); • ruler; • a pencil; • scissors; • glue (better PVA). The most difficult thing is to develop and draw sweeps, at least basic knowledge of drawing is needed. You can take ready-made sweeps and print on the printer.
To make the fold line smooth and sharp, you can use a blunt needle and a metal ruler. When carrying out the line, the needle must be strongly bent in the direction of movement, practically putting it on its side. This is the unfolding of the triangular pyramid. This is the unfolding of the triangular pyramid.
This is the unfolding of the cube. This is the unfolding of the octahedron (tetrahedral pyramid). This is the unfolding of the dodecahedron. This is the unfolding of the icosahedron.
Here you can find patterns of more complex figures (Plato's bodies, Archimedean bodies, polyhedra, polyhedra, different types of pyramids and prisms, simple and oblique paper models ). By the way, to calculate the parameters of the pyramid, you can use this program.
2 Self-made paper shapes can be used not only for entertainment, but also for training. For example, you can visually show the child how this or that figure looks, let it hold in your hands. Or you can print out schemes with special symbols for the purpose of learning. So I suggest below to get acquainted with the dodecahedron dome, both simple and with small drawings that will only attract the attention of the kid and the training will make it more fun and entertaining.
