Creating crafts with their own hands is interesting not only for children, but for adults. However, for adults, a sufficient number of models are invented, which differ in the complexity of the implementation and the time spent on their creation. Recently, adults and children have an interest in creating complex geometric figures. To this form of figures is the icosahedron, which is a regular polygon and is one of the Platonic solids - regular polyhedra. This figure has 20 triangular faces (equilateral triangles), 30 edges and 12 vertices, which are the junction of 5 ribs. The correct icosahedron of paper is difficult to gather, but interesting. If you are keen on origami, then making an icosahedron paper with your own hands will not be difficult. It is made of colored, corrugated paper, foil, packaging paper for flowers. Using a variety of materials, you can give even greater beauty and spectacularity to your icosahedron. Everything depends only on the imagination of its creator and the handy material on the table.

We offer you several versions of icosahedron scans that can be printed, transferred to thick paper and cardboard, bent along lines and glued together.

How to make an icosahedron of paper:
In order to assemble an icosahedron from a sheet of paper or paperboard, you must prepare the following materials in advance:
- mock-up of the icosahedron;
- PVA glue;
- scissors;
- ruler.
- Print out a mock-up of the icosahedron on a piece of paper.
- Cut it out by punctuation. This is necessary in order to have a free place to glue the parts together. It is important to cut out the icosahedron as slowly as possible, because at the slightest shift the artifact will eventually look ugly. This need for a more accurate cutting is due to the fact that all triangles in the icosahedron have the same sides, and if any side will differ in length, in the end such a discrepancy in size will catch your eye.
- We fold the icosahedron along solid lines.
- With the help of glue we glue the places delineated by the dashed line, and connect the neighboring sides of the triangles. It is necessary to hold in such condition each glued side for 20 seconds for more dense fixation. Similarly, you need to glue all sides of the icosahedron. The last two ribs represent the greatest difficulty in bonding, since they require skill and patience. Icosaedr is ready.
When creating an icosahedron, it is important to pay special attention to the process of bending all the details: in order to evenly bend the paper, you can use the usual ruler.
It is noteworthy that the icosahedron can also be found in everyday life. For example, a soccer ball is made in the form of a truncated icosahedron (a polyhedron consisting of 12 pentagons and 20 hexagons of regular shape). This is especially evident if you paint the resulting icosahedron in black and white, like the ball itself.

Such a soccer ball can be made independently by printing a preliminary scan of the truncated icosahedron in 2 copies:
Creating an icosahedron with your own hands is an interesting process that requires thoughtfulness, patience and a lot of paper. However, the result obtained in the end will please the eye for a long time. An icosahedron can be given to play to a child if he has already reached the age of three. Playing with such a complex geometric figure, he will develop not only imaginative thinking, spatial skills, but also get acquainted with the world of geometry. If an adult decided to create an icosahedron on his own, then such a creative process for the construction of an icosahedron will allow time to pass away, and also boast of his close ability to create complex figures.
