**Checked and updated – August 2013.
Coming very soon (January 2015) – a completely revised version.**

This post remains one of the most popular on this blog. So – time for a revisit and an update. Most of the original post still stands – a few additions rather than deletions. Any post claiming top 10 or >10 in my case is clearly ** the author’s** top 10, not

**top 10! These are**

*the**top >10 because I really do use them –*

**my****a lot**– in the classroom!

…and a slide show to summarize… (download PowerPoint file: **top-10-mathematics-websites-v3**

(pdf version: **top-10-mathematics-websites-v3** **)**

(Some hyperlinks seem to be behaving inconsistently in Slideshare).

I was asked about my own top ten Mathematics websites, this request and remembering **Edna Sackson’s comments** on her ’10 Ways…’ series reminded me of the various ‘Top (insert number here) Mathematics Websites’ posts I have read; all of them have left me with the thought that so many excellent sites are missing from such lists. Really such posts (including this one) should be titled ‘My Top 10….’ as they understandably include the author’s favourites. For my own list I have decided to include some categories as well as individual sites which gives me the excuse to mention far more than 10! Note that every site mentioned here is free to use.

So in no particular order:

**CIMT**– The Centre for Innovation in Mathematics Teaching, from the University of Plymouth, an astonishing resource – free curriculum materials for all school-age students. Here you will find examples, exercises, teachers’ notes, activities…..

For example if we look at the**Year 7 page**as well as all the book chapters with their numerous worked examples and exercises there are also teachers’ resources including notes, slides, revision tests, activities and**mental tests**on each topic. The activities are varied and include investigative work.

There are also**Interactive Tutorials available**, useful for revision or perhaps if a student has been absent and several**Topical Applications of Mathematics**which include lesson plans and student resources. I have successfully used the resources on**Braille**. On the subject of interactive materials – note the**Step Up to A-Level Maths resources**.**Nrich**– a favourite site I return to again and again. The site has extensive resources including problems, games, interactives and articles for teachers. Choose the stage required from Teachers’ or Students’ menus on the front page. Choosing**Secondary**under Teachers for example includes a link (under Collections) to an excellent**stage 3 and 4 curriculum page**which suggest NRICH activities by curriculum topic. Also, very usefully, activities are listed by mathematical processes such as Thinking Strategically and Working Systematically. Note also the link to the (updated) mapping document which is very valuable when searching for activities. It is also possible to**Search by topic**and**Activities organised by topics**are also available on student pages. The**Other Resources collection**includes the excellent poster collection as well as a wealth of other resources. The guides for Students and Teachers include links to register for newsletters.

**For the Interactive Whiteboard there are many outstanding interactives.**-
**WolframAlpha**– a computational knowledge engine which is rather good at Mathematics (as well as many other subjects!).This is so useful for checking solutions or exploring many examples. I have written**separate pages on WolframAlpha**here including**slideshows**to demonstrate syntax. There is a post written for students with some questions to try on my**Mathematics for Students**blog.

**Graph Plotters**– there are many free and easy to use online graph plotters. I like using resources like this in class that students will then be able to use themselves at home. The superb**graphing calculator**from Desmos allows you to easily plot one or more graphs, including lines of the form x=k. It is also possible to illustrate inequalities. See**this page**for more information.

Sites like**GraphSketch**or the**Function Grapher**from Mathisfun are simple enough for younger students to use and allow the user to plot functions and get a permanent url to the graph.**Software**– a list like this would be incomplete without mentioning**Geogebra**for interactive Geometry. This is a sophisticated program and much support is available online in the form of videos and tutorials. I have included some useful links in**this post**. From MIT**Scratch**is an object-oriented programming language which is an excellent resource for teaching students programming skills as well as doing Mathematics.

**Microsoft Mathematics 4**provides a graphing calculator that plots in 2D and 3D, step-by-step equation solving, and useful tools to help students with math and science studies.**Notes and Exercises –**If we asked the students for their top ten Maths websites I know most of mine would include BBC bitesize (see**BBC Bitesize KS1**(ages 5-7),**BBC Bitesize KS2**(ages 7-11),**BBC Bitesize KS3**(ages 11-14),**BBC GCSE Bitesize**(ages 14 – 16) also**BBC Skillswise**although aimed at adults, this site has information on basic Mathematics (and English) skills useful for any age) and**mrbartonmaths.com**for his**very helpful notes.**Note that both of these sites also have many resources for teachers. Try David Watkins’ high quality**Dynamic Maths Worksheets**which you can use to generate all the practice questions you ever wanted! Trinity School have helpful**Mathematics resources**with many examples to try (answers included).

**Math is Fun**has already been mentioned for its graphing tool, it has extensive resources. Choose Algebra for example and you will find everything from a basic introduction through to completing the square, the definition of a function and sequences. Many universities make excellent notes available online for all students. See**this Evernote shared notebook**(no login is necessary and you do not need an Evernote account to use the Notebook). The**mathcentre**in particular has a great variety of resources including videos.

**Applets / Demonstrations / Manipulatives**– There are many great sites in this category, I know common searches which send people to this site are for the excellent**Wisweb applets**. John Page’s**Math Open Reference**includes some excellent demonstrations on constructions. Search by technology type on the**MathsTools site –**this**article by Bethany Hudnutt**is on the navigation of the site. Two more excellent sites are the**National Library of Virtual Manipulatives**and Spencer Riley’s**Teacher LED**site of interactive whiteboard resources.Mike Hadden has a superb collection of Excel files on his

**Maths Files site**which can be used to demonstrate and explore many topics in Mathematics.**Problems**– There are several excellent sites providing resources for problems – many are highlighted on the**Rich Tasks page**. Another outstanding source of problems can be found on**A+ Click Math**. See also the various**Mathematics challenges**. I have**page on the blog**listing various sites with excellent problems.**Games**–**Manga High**has high quality games to help students learn Mathematics. Schools with accounts (and Manga High is now completely free in several countries including UK, Ireland, USA, Canada, all of Scandinavia and the Indian subcontinent) also have access to their numerous and very clear Prodigi lessons and quizzes which teachers can set for their classes. A site with many games to practise numeracy skills at 10 different levels is**Sumdog**(further information including the topics covered and instructions for students in**this post**). Nrich gets another mention for its excellent games – my own favourite Nrich games and many other games and puzzles are on a companion blog**Mathematics Games.**

**Online communities, resource sharing & blogs –**finally I would not be without the various online communities and resource sharing sites;**The National STEM Centre**is an outstanding example. Thanks to the many teachers who share excellent resouces, superb examples are**Mathsbox**and**JustMaths**which I use regularly; I have also used many resources from**David Millward’s PowerPoint collection**.**TES**for forums and**resources**,**NCETM**,**The Guardian Teacher Network, Mark McCourt’s Emaths,**also**Twitter**which if one follows the right people can be a great source of ideas and information. For plenty of reading and great ideas try these various**excellent blogs.**

There is a version of this post written for students on **Mathematics for Students**.

Don’t forget to look at the resources available on the National STEM Centre eLibrary. Read Colleen’s excellent write up https://colleenyoung.wordpress.com/2013/09/29/national-stem-centre/

It’s colleenyoung.wordpress.com!!!!

Thanks a lot for the endless suggestions both in terms of great resources but also in terms of organisational issues.!

My resolution for the next term is to not only marvel your great ideas but to put one suggestion into practice each week. By just concentrating one one good idea per week I hope to transfer lots of good ideas from my ‘passive’ into my ‘active’ resource bank!

Thanks again.Ax

Hi Damian. I agree with all your recommendations – in fact you will see mrbarton is included in this article – see under my Notes category.

You will also find Kenny’s pouch and suffolk maths within these pages – see Progression – https://colleenyoung.wordpress.com/app/

CIMT – no I am not joking! I did say it was my top ten! Though I know many refer to CIMT – it’s just so comprehensive – if one is ever stuck you can find an example there. Some of the activities are rather nice, the mental tests on every chapter can provide good starters and the interactive materials can be useful for students for independent study.

Glad you like the filling and pouring – I have used the CLEO resource for years and only recently discovered The Connected Maths Project.

Please say you are joking about the entry of “CIMT- The Centre for Innovation in Mathematics Teaching” in your top 10! It is death by worksheet, there is no innovation on the website,and it is very dated. I would recommend the following http://www.mrbartonmaths.com/ – a truly brilliant site, also http://kangaroomaths.com/kenny.php another great site or http://www.suffolkmaths.co.uk/

These are great with some great teaching and learning activities.

I did enjoy filling and pouring links – great job.
