Tools/materials: cardboard, scissors, pens.

2. Draw the following figures on the cardboard with small squares, arrange four squares of the same size horizontally, and draw another square of the same size from the top and bottom of the second square from the right.

3. Cut it along the periphery of the square with scissors.

4. Fold each side of the square.

5. surround each small square and stick it with tape to make a cube.

For children, origami games have many benefits. Origami can exercise the flexibility of children's fingers and develop their hands-on ability and innovation ability; Things in life, small animals, vehicles, etc. Become an image origami. In this process, children's spatial imagination will also be improved.

For the elderly, origami games can not only help them use their brains, activate their thinking, and achieve the overall coordination of the trinity of hands, eyes and brain, but also prevent the memory of the elderly from declining. Some sanatoriums use origami as a treatment for patients' rehabilitation.

The "origami mathematics" derived from origami art is proved by equations: theoretically, any geometric form can be simulated by origami. With the help of computer software aided design, today's origami researchers can fold more complicated graphics than before.

In Kamiya Satoshi, a 2m× 2m square paper was folded into a dragon, and its scales and claws were clearly visible. It is said that there are probably no more than 20 successful origami people in the world.

On the other hand, modern origami is not only an art, but also a new science: origami mathematics. It has been applied to the solar panels of artificial satellites, the storage methods of automobile airbags, and even the structural design of the Hubble Space Telescope, all with the help of origami mathematics.
