Abstract

Overview Students will work in groups to design a manual calculating machine using a cardboard and strips of paper with numbers and signs printed on them. They will then test the machine by performing some basic mathematical operations on it like addition, subtraction, multiplication and division to make sure their machine is working accurately. Objective Design and build a calculating machine using cardboard. Perform basic mathematical operations using the machine. Understand how to use different materials to construct the machine. Develop higher order thinking skills by discussing with each other how they can upgrade the machine to perform more complex mathematical operations on it. Teacher will explain to the students about the activity they are going to perform, the materials required for it and the steps to be followed. The teacher will also tell the students how to perform mathematical calculations using the machine once the students are done building it.
