[0002] In the process of teaching mathematics to children, because children are young and have weak abstract thinking ability, they need to use intuitive and vivid demonstration tools to understand mathematical concepts and knowledge.

[0003] Currently available mathematical teaching demonstration devices are either overly complex, difficult to operate, and unsuitable for children's cognitive levels, or have limited functionality and cannot meet diverse mathematical teaching needs, such as teaching numerical operations, shape recognition, and spatial concepts. Therefore, designing a simple, easy-to-operate, feature-rich mathematical teaching demonstration device that aligns with children's cognitive characteristics is of significant practical importance. In light of this, we propose a mathematical teaching demonstration device. Utility Model Content
