Another Angle on Angles
Clausen-May, Tandi
Australian Primary Mathematics Classroom, v13 n1 p4-8 2008
The impact of written and printed texts on the geometry curriculum has a very long history. Static diagrams, static definitions, and static proofs have dominated the classrooms for centuries. Geometry is about shape and space, and about the relationships between shapes in space. Movement is a key aspect of those relationships, but movement cannot be shown in a printed text book, so it is relegated to a minor role in the primary mathematics curriculum. One area where print has had a particularly significant effect is in the teaching and learning of the concept of angle. An angle is a measure of turn. It is a measure of movement, not a shape. In this article, the author describes a dynamic approach used to develop the concept of angle as a measure of turn. (Contains 11 figures.)
