Addition, subtraction, multiplication and division teaching aid: Made of high-quality wood, it includes an operation board and wooden blocks with numbers/symbols. It is specially designed for children over 36 months old. Through practical operation, children can understand the rules of arithmetic operations and develop their number sense and logical thinking Safe and environmentally friendly material and craftsmanship: The wood is processed with rounded corners, resulting in a smooth surface without burrs or rough edges, and it has no unpleasant odor with a uniform texture. The edges of the number symbol blocks are rounded and of moderate size. The base plate is stable and anti-slip, ensuring the safety of children's operation Arithmetic operations and logical: Guide young children to demonstrate addition, subtraction, multiplication and division using blocks on the arithmetic board (for example, place the numbers and symbols for "3 + 2"). This makes abstract arithmetic concrete and helps establish the logic of arithmetic Fine motor skills and hand-eye coordination: Precisely grasp the wooden blocks and place them at the corresponding positions, which helps to train the fine control of the hands, the strength of the wrists, and the hand-eye coordination ability Parent-child interaction and independent thinking: Support family collaborative games (such as "setting questions - solving questions"), promoting communication and cooperation through interaction; Encourage children to independently verify the results and cultivate problem-solving skills
