Montessori Sensory Area Classic Core Teaching Tools: Specifically designed for children, featuring the standard international color palette set. It includes three boxes of color cards of different hues, serving as the standard tool for Montessori color education. Through visual matching, pairing, and categorization, it helps develop acute color discrimination and aesthetic awareness Multisensory Graded Training: The color palette is divided into the first box (basic colors), the second box (graduated colors), and the third box (mixed colors). Children progress from simple to complex, using visual comparison and tactile perception to distinguish hue, lightness, and purity. This aligns with Montessori's "sensory first" educational principle, laying the foundation for artistic aesthetics Safe and Natural Beechwood Material: Made from imported beechwood wood, the edges of the color cards are smoothed and free of burrs. The color is pure and odorless with water-based paint. The beechwood trays have clear compartments, meeting the high standards of Montessori professional teaching tools. They are safe, durable, and reusable Fine Motor Skills and Logical Thinking: Children grasp, place, and pair the color cards, which optimally exercises fine motor skills, hand-eye coordination; in color classification and gradual arrangement, they develop observation skills, logical reasoning, sequence sense, and concentration Universal Scenario for Kindergartens/Families: Compliant with international Montessori teaching standards, it is suitable for the sensory area/art area in kindergartens, and also suitable for family early education. It is an ideal auxiliary tool for conducting Montessori sensory activities such as "color pairing, gradual sorting, and free creation."
