I wanted to point out that I have several Math Glossaries on my website under Math section. They include:

* Ron Blond’s Math Glossary, which is in English-only, but has excellent animated examples of each word.

* McGraw-Hill’s Multilingual Glossary, which translates math words into thirteen different languages (including Hmong).

* Jenny Eather’s fine Math Dictionary.

* Houghton-Mifflin’s eGlossary, which provides audio support for everything you see on the screen.

* HRW’s more advanced Multilingual Glossary.

* Harcourt’s Math Glossary, which also provides audio support and images.

All of them are accessible to English Language Learners.
