Color work to enhance proof-writing in geometry

Abstract

The strategies we have illustrated here are to color-code as a tool (1) of
representation for facts and (2) for understanding of relationships. Such
color-coding can assist students in packing and unpacking information and
managing the complexity of proofs and proving. Furthermore, it may be that
teachers can better assess how a student is approaching proof writing based on
the color scheme utilized by the student. It provides teachers with a tool to help
communicate with individual students and their different approaches to proof
writing.
