**This Diigo list** (click on the green links to go direct to the site and then back on your browser to return to the list) has several useful dictionaries and other useful reference material for Mathematics students. **See Jenny Eather’s dictionary for example **and note the section on **charts**. Also very useful is this **glossary for teachers**. It’s really good for students too as it defines vocabulary used in Mathematics from Key Stage 1 to Key Stage 4 (Ages 6-16). For the terminology used in question papers see this docment: **maths_exam_terminology (**I have seen this document around the web, I believe the original is from AQA).

Some students may have seen the excellent credit card size information sheet full of **mathematical formulae from Loughborough University**. This is also available as a free app for your mobile phone. Apps for GCSE (ages 14-16) and A Level are available.

For older students perhaps try **Wolfram MathWorld** or **The Mathematical Atlas**. Note that that is possible to obtain a definition from WolframAlpha – for example try **complex number **for various examples with complex numbers and note that you can choose to look at the **mathematical definition **also.

Or perhaps try the **Mathisfun dictionary.**

Note that ** Diigo** is a social bookmarking tool which allows you to store your favourite websites online and share them with others. This means you can access your favourites from any computer.

I’m glad it’s helpful Clara. I know lots of students and teachers like Jenny Eather’s dictionary for example.

Very useful for students Colleen. Please visit my blog http://mathematicsbhilai.blogspot.com/ . I am also using it for students.

Hi Sanjay – it’s good to see teachers writing for their students!
