Strip assembly teaching tool, composed of multiple plastic strips of different colors and lengths connected by connectors. It can be used in mathematics teaching to help students intuitively understand the properties of geometric shapes, such as demonstrating the stability of triangles and the instability of quadrilaterals through concatenation; Auxiliary score and proportional teaching, using bars of different lengths to represent numerical relationships. In class, graphic collage activities can be carried out, allowing students to fully unleash their imagination and creativity by using these plastic strips to construct various shapes and structures. Cultivating spatial thinking and hands-on abilities is a practical tool for mathematical enlightenment and practical teaching.
