Teaching Math Words That Start With T

I know this about Math and Science, if your students understand the basic prefixes, roots, and suffixes; they'll be able to discern the meaning of more terms.

For instance the suffix tri-. Almost any word that begins with this suffix means that there are three of what the root word indicates. A triangle has three angles, a tricycle has three wheels, etc.

I went all the way through two degrees not seeing truncated cuboctahedrons (what are these doing in children's Math books?!), but at a glance I know that the word truncated means that something is cut and I can see the octa meaning eight and I'll bet that I could have gotten a multiple choice test question right just knowing these definitions.
