Fraction Miniature Sensory Teaching Aid: Made from high-quality wood and hand-polished, it includes detachable miniature figures (divided into 1/1, 1/2, 1/3, 1/4, etc. portions), designed specifically for children over 36 months old. By disassembling and understanding the relationship between the whole and its parts, it helps establish the concept of fractions Safe and environmentally friendly material and craftsmanship: The wooden components are rounded at the corners, resulting in smooth surfaces without burrs. They are coated with non-toxic and harmless water-based paint. The colors are clearly distinguished in separate sections, ensuring precise assembly and preventing loosening, thereby ensuring the safety of children's operations Fraction cognition and logical thinking: Guide children to separate and recombine fraction figures, visually perceive the concepts of "equal division" and "whole-part", and cultivate their observation skills and fraction-preparation thinking Fine motor skills and hand-eye coordination: Grasping small pieces precisely and assembling them, which exercises the fine control of the hands, the strength of the wrist, and the hand-eye coordination ability Concentration and interest in mathematics: Through repeated decomposition and combination, cultivate patience and concentration. In the process of operation, stimulate curiosity about mathematics and lay the foundation for the study of abstract fractions
