Should you use a math dictionary? This is the blog post at Homeschool Math Blog that suggested making a dictionary (or a lap book) of math terms.

I liked the idea. Having a little book that Justin, when he is old enough, can write in different math terms that he learns.
Let your child/student make their own math dictionary! Just make a new page in it every time there is a new concept or term to study. The student can write the term, write an explanation, an example calculation, or draw a picture of it − or all of those.

Making such a math vocabulary book shouldn't take lots of time, because you don't usually encounter new words every single lesson in a typical math curriculum. The rest of the time the book can act as a reference or as a review medium.

There is one exception though, and that is GEOMETRY. In geometry, just about all the time you have new terms to learn. In fact, a big part of the geometry in elementary grades is simply learning the meaning of words such as parallel, perpendicular, trapezoid, vertical angles, symmetry, diameter, radius, circumference, and so on.
Anyways, go there to read the rest of the post. Thought it interesting, and worth remembering. :)
