For elementary to junior high school students. You can visually confirm the shape and area of the cut surface, as well as the volume of the cut body, instead of just imagining them in your head! 【3 Features of IQ Design Puzzle】 ★ Non-slip Parts stick together, making it easy to assemble and fun to play with! ★ Unbreakable It won't break even if dropped, so it's safe. ★ Soft It feels soft to the touch and won't hurt even if bumped. From the instruction manual... The Doctor's 1Q Design Puzzle is a puzzle devised to cultivate children's spatial reasoning abilities through fun play. Spatial reasoning problems dealing with the cutting of solids, as seen in entrance exams for private junior high and high schools, are very difficult for children. This is difficult to cultivate through studying at a desk alone. The ability to imagine the cut surfaces of all kinds of solids (spatial reasoning ability) is gradually cultivated through experiential learning using solid models, etc... The box is damaged, but the main body and instruction manual are relatively clean. Thank you.
