This book introduces origami infused with Fröbel's philosophy of creative character education. Origami, which has continued to develop as a way to nurture math, science, art, and creativity, can be enjoyed across generations, from young children to adults. The book covers projects such as the tetrahedron, octahedron, icosahedron, pentagram on a hexahedron, swan cube art, and square boxes. From the geometric beauty of shapes to works that blossom into lyrical, expressive art, and pieces that feel like exciting puzzles, this book presents example works from Fröbel's perspective. It also introduces a new world of formative art called "Cube Art," a fusion of art and geometry, helping readers explore the world of creative origami and cube art in new ways.
