① This interactive GeoGebra example demonstrates how tape diagrams (bar models) can visually represent algebraic equations and inequalities, making abstract relationships concrete. ② Core math concepts include algebraic expressions, equations, inequalities, proportional reasoning, and the connection between geometric shapes and algebraic operations. ③ Construction uses GeoGebra commands such as Textfield for input boxes, Polygon for drawing bars, Point and Segment for key points and segments, Midpoint for midpoints, and Sequence for repeated structures, with objects like g, e, m, poly1, and list1 linked dynamically. ④ Suitable for middle and high school algebra instruction, helping students grasp variables, equation manipulation, and solution sets; ideal for classroom demonstrations or self-paced exploration.
