Mathematics Glossary is a free interactive math reference tool for students of all ages. It’s also useful and a refresher for parents and teachers. You find the math term, such as addend or histogram, using their alphabetic index. Or you can look at a list of relevant terms by grade level. The site provides a definition of the math term, graphic examples, and, in some case, real life examples.
This glossary is still a work in progress. Terms used up to grade 6 are complete, but less than half are accessible for the higher grade levels.
