On October 4, 2022, the fourth day of the National Day holiday, Guona Technology Jiang accompanied the children to complete the three-dimensional geometric origami task arranged by their school. Our goal is to DIY create a robot built from three-dimensional geometric figures. I personally think it is very meaningful!
Guona Technology Jiang believes that origami is very important for geometry teaching in mathematics. This process not only has educational functions, but also has entertainment significance, which arouses children's interest in geometry . However, because our education was highly utilitarian in the past, this teaching method faced challenges and resistance from all aspects, so its application value and usage methods have not been popularized yet. It will only be moderately involved in some distinctive schools, such as Wuxi Foreign Language School , etc.
This task is the most difficult (after proficiency, it is actually very simple), and the most workload is to fold the hexahedron. Here is the following:
Step 1: Prepare origami in more than 3 colors
Step 2: Cut origami to get squares of 3 sizes
Step 3: Fold the crease in half, then expand
Step 4: Fold two corners into triangles
Step 5: Fold half along the crease
Step 6: Left and right side Fold
Step 7: The upper left corner is opened and put into the inner
Step 8: The lower right corner is also like step 7, and put into the inner
Step 9: 1 face of the hexahedral complete
Step 10: According to the diagram, two corners are folded into triangles
Step 11: The same method is folded 6
Step 12: Combination, the feet (the pointed part) are inserted into each other
Step 13: Two are the same The components of the same color are combined by the two sides, which makes it more beautiful
Step 14: Finally, insert the two sides intertwined and interlaced, so the hexahedron is more solid
6 regular hexahedrons of different sizes. After completing the robot construction process, I personally think that the most creative steps in the robot construction process have come. Here is the following:
- Find a used can , wrap around colored paper as the body of the robot
- string the smallest hexahedron together with a toothpick. As a robot, the receiving antenna
- is connected to the key parts of the robot's head, hands, feet, etc. with double-sided tape
- and then use marker pen to outline the robot's eyes, mouth, clothes worn by the robot, etc.
- Finally, it is fixed with a base with a certain amount of
After the construction is completed, the robot is not very beautiful, but it is full of cuteness. In addition, the used cans are recycled in the process, which also reflects green environmental protection and has obvious educational significance.
In short,
I am @Guona Technology Jiang , a popular science writer; a creator of the Baijia Craftsmanship Program, and a creator on the Baijia List; a senior operation in the technical background, rooted in the fields of empty cleaning, new materials, energy conservation and environmental protection for 20 years, bringing you a different scientific understanding from a calm and professional perspective.
