Abstract

This article presents a task in which students explore how to help a shopkeeper decide the best deal for purchasing soaps from three different wholesalers. The students express the options in the language of mathematics to find the cost for a certain number of soaps. They further write linear equations to find the changeover point at which a different shop becomes a better deal. The exploration task lets students “get inside” the mathematics and appreciate how algebra can be used in decision making. This task is suitable for students of classes 8 to 10. It covers the content domains of Arithmetic, Algebraic Expressions, Linear Equations and Coordinate Geometry.
