You can learn by actually holding, observing, assembling, and disassembling them. Because they are made of transparent material, you can see the internal structure and the relationships between faces, edges, and vertices at a glance, which is perfect for developing spatial awareness and geometric sense. Using the included 3D unfolding cards, you can also intuitively grasp the unfolded diagrams and the concepts of area and volume. It can be widely used from lower to upper elementary school grades, and is also ideal for home study, review, and parent-child educational time. By allowing children to manipulate the shapes with their own hands, their interest and understanding of math will deepen significantly. • Transparent 3D models allow for an intuitive understanding of the structure and characteristics of shapes. • Can be disassembled and assembled, allowing for fun learning while using your hands. • Comes with unfolding diagram cards to support the study of area and volume. • Spatial awareness, logical thinking skills, and observation skills are naturally acquired. • Can be used for a long time from 1st to 6th grade elementary school, and is also ideal for home study and exam preparation. • Working on it together with parents expands communication and the enjoyment of learning. • Improves understanding for children who are not good at math by using concrete objects. ※ The models, unfolding diagrams, and instructions will be packaged and shipped without the box. 【Size】 Please check within the images. ※ Please understand that there may be some errors. 【Material】 Plastic, paper Educational toys, 3D shapes, transparent shapes, math教材, spatial recognition, unfolding diagrams, area, volume, learning materials, home study, home math, parent-child learning, elementary school students, math, shape puzzles, STEM education, Montessori, exam preparation, educational toys, overcoming math difficulties, shape recognition, developmental support, brain training, kindergarten entrance exams, elementary school entrance exams, junior high school entrance exams, exam preparation, kumon, gakken, kogumakai, Pygmalion, Shichida method, early education, Nichinoken, sapix, learning resources, gifts, grandchildren, presents
