Shapes with Sutli: The String Game

This article describes an activity where students created different geometrical shapes using a closed-loop string and developed conceptual understanding by engaging with properties of the shapes. The activity encouraged them to think deeply about the meaning of points, straight lines, edges, faces, and angles of geometrical shapes. Using standard models which are generally available, students only get to view geometrical shapes or build them by following a set of instructions. However, the activity described here provided students the opportunity to interact with each other, build various shapes and think creatively about how to prove their properties, thus, developing an in- depth understanding.
