Montessori Mathematics Area Geometric Teaching Tools: Specifically designed for children aged 12 months and above, the classic Montessori square puzzle board (square tangram) is an essential tool for introducing Montessori geometry and spatial cognition. Through different shapes and colors of the pieces, it helps children build geometric shape recognition and spatial relationship understanding Multisensory Immersive Geometric: Children can grasp, assemble, and combine the pieces themselves, converting abstract geometric concepts into tangible tactile experiences. Combined with visual and tactile stimulation, it aligns with the Montessori "learning through doing" principle, allowing children to truly understand the essence of shapes, angles, and combinations Safe and Natural Birchwood Material: Made from imported birchwood, the puzzle board and pieces are polished to a smooth edge without any sharp edges. The environmentally friendly water-based paint has bright colors that do not fade. The pieces fit together perfectly, meeting the safety standards for infant toys, and are safe for children to chew on, grasp, and play with Fine Motor Skills and Logical Thinking Dual Enhancement: Children can grasp, pair, and fit the pieces, exercising finger grip strength and hand-eye coordination skills. In the process of combining, separating, and assembling, they develop observation skills, logical reasoning, and spatial imagination, laying a solid foundation for geometry and spatial thinking Universal Teaching Tools for Kindergartens and Families: Compliant with international Montessori teaching standards, it is suitable for the Montessori mathematics area in kindergartens and also suitable for family parent-child interaction. It supports children in independently completing tasks such as assembly, combination, and creative shaping, cultivating their learning autonomy and curiosity
