◎This is a 3D puzzle that allows children to learn while having fun with the shapes and patterns created by cutting a cube diagonally. There is literature that shows that 3D puzzles are effective in improving children's spatial IQ and mental rotation. ◎When a solid object is cut diagonally, it is possible to create cut surfaces that are equilateral triangles or regular hexagons by combining them. In this way, three-dimensional shapes that could only be imagined up until now can be visualized. This idea has been patented. ◎In order to understand the difficult problems of cutting three-dimensional objects in mathematics, it is very important to see the actual shape with your own eyes, understand it, and experience the joy of "I get it!" ◎The three-dimensional cutting problem, which is frequently seen in junior high school entrance exams, is very difficult because it requires cutting a cube diagonally and imagining the cross section, shape, area, and volume on paper. Solve it easily with this puzzle! ◎We have devised a way to make it easier for children to understand by using graph paper of the same size as the blocks on the back of the instruction manual and experiencing the unfolding diagrams of difficult problems. ◎ Use this "Dr. IQ Puzzle Sticking" as a study aid to help develop three-dimensional comprehension and various other abilities.
