Montessori Sensory Area Core Teaching Tools: Specifically designed for children, the classic geometric pegboard set enables children to visually construct geometric shapes such as squares, triangles, and polygons through wooden pegs and colored rubber bands, helping them understand shape structures and spatial relationships and establish basic geometric thinking Multisensory Immersive Learning: Solid wood pegboard + replaceable graphic cards. Children insert wooden pegs, pull rubber bands, and assemble graphics by themselves. Combined with visual and tactile stimulation, it conforms to the Montessori "learning through doing" concept, strengthening geometric cognition and eliminating rote memorization Safe and Natural Beechwood Material: Made from imported beechwood, the pegboard and wooden pegs have rounded edges without burrs, and the environmentally friendly water-based paint is non-toxic and odorless. The rubber bands are highly elastic and durable, meeting the high standards of Montessori professional teaching tools and being safe and durable Fine Motor Skills and Logical Thinking: Children insert wooden pegs, pull rubber bands, and adjust graphics, exercising finger grip strength, wrist control, and strengthening hand-eye coordination. In the process of assembling, they understand the corresponding relationship of points, lines, and surfaces, cultivating concentration, spatial imagination, and logical reasoning abilities Universal Teaching Tools for Kindergartens/Families: Compliant with international Montessori teaching standards, suitable for the Montessori mathematics area/sensory area in kindergartens, also suitable for family parent-child interaction, guiding children to independently create graphics, and cultivating their learning autonomy and creativity
