Overcoming confusion with the MATHOMAT protractor through a better understanding of angle

Summary

Student’s understanding of angle is made difficult by the absence of a single definition of it as a target quantity. This workshop focuses on how students develop a concept of this important, but often poorly understood, measurement quantity. We explore the several different concepts of angle that need to be understood in middle school. Our workshop shows how students can learn to unify these concepts into a single, visually based, understanding of angle through drawing activities using the Mathomat template and its associated student book. The aim of these activities is to overcome the problem, identified in major research studies, that the structure and purpose of protractors as a tool are opaque to many students; leading to greater skill and confidence with the use of protractors as a tool. This workshop uses the new Mathomat v2 geometry template and student book.
