Parallelogram in Motion – Explore Sides and Angles

INNOVATIVE MODEL

During my B.Ed Teaching Practice Phase II, I developed an innovative working model based on the Class VII chapter Parallelograms to make geometric properties more concrete and engaging. The model was constructed using four equal scales and four full-circle protractors joined with drawing pins to form a movable parallelogram. This simple, low-cost setup allows direct measurement and observation of properties such as opposite sides being equal and parallel, opposite angles being equal, and adjacent angles summing to 180°.



The model was used to help students of Class VIIB verify these properties through hands-on interaction rather than only textbook diagrams. It also helped demonstrate that rectangles, squares, and rhombuses are special types of parallelograms. The activity created strong student interest and participation, showing how innovative, model-based teaching can make mathematics more visual, interactive, and meaningful.
