Developing Student-Teachers’ Understanding of Geometrical Figures/Objects Using a Bicycle Rubber Tube

This paper addresses the ways that a bicycle rubber tube can be used to develop learners’ understanding of geometrical figures/objects. The use of a bicycle rubber tube is important because student-teachers and in-service teachers can use the material to teach learners in schools to understand various geometrical figures/objects. In doing so, geometrical figures and objects, metric, and metric space are understood relationally. Using a bicycle rubber tube, it was found that various geometrical figures and objects were formed, including rectangle, triangle, square, and pentagon. The finding has implications in teaching geometrical figures/objects, including teachers can use a bicycle rubber tube to develop learners’ understanding of a circle, rectangle, triangle, square, pentagon and hexagon.
