Junior High School Entrance Exam Preparation: Cube Cross-Section 3D Models - Math, Solid Geometry, Complete Set of 15 Types - Spatial Reasoning Traini

Junior High School Entrance Exam Math Preparation: A learning material that allows you to study the most difficult unit, "Cutting a Cube," using actual 3D models. You can physically examine the shape, position, and connections of the cut surfaces, enabling you to acquire spatial awareness that is difficult to understand through diagrams or just thinking about it, in a visual and tactile way. Includes 15 types of cut surfaces: A comprehensive set covering frequently appearing patterns in entrance exams, including triangles (equilateral triangles, isosceles triangles), quadrilaterals (squares, rectangles, rhombuses, parallelograms, trapezoids), pentagons, and hexagons (regular hexagons). Practical learning method: By taking out the model corresponding to the cutting conditions in the problem statement, checking the shape of the cut surface, the number of edges, and the positional relationships, and copying it into a notebook, you can effectively acquire the ability to convert from 3D to 2D. 3D printed for realistic reproduction: Cut surfaces passing through vertices and midpoints of edges are precisely reproduced as actual 3D shapes. This "real-world diagram" allows children who struggle with spatial reasoning to understand a 30-minute explanation from a tutor or private instructor in just 10 seconds, helping them to improve their spatial reasoning skills. Translucent case included: A translucent case is included to hold and observe all 15 models. As this is a 3D printed product, fine layering may be visible on the surface, but this does not affect the quality as an educational material.
