Chapter 4. Graphic Representation in the Mathematics Classroom

by Loretta Heuer

Is your first instinct a numeric one in our familiar base-10 system, or perhaps in systems based on other numbers such as 4 or 12? Or do you think of base as part of a geometric figure? Did you envision the base of a polygon, which would be a line? Or of a polyhedron, which would be an area?
