The learning of mathematical concepts can be aided by the useof tech-nology and graphical visualization. The use of modern toolscan greatly enhance the
learning experience by encouraging inquiry and deepening one’s understanding. In
this chapter triangular, square, and polygonal-like numbers are explored in context
using spreadsheets. The context provides the element of relevance that learners need
in order to appreciate concepts that might otherwise seem abstract in nature.
Keywords: contextual problem solving, arithmetic sequences, polygon-like numbers
