I have enjoyed books for as long as I can remember and have several Maths books on my Kindle, some of which were free or very low cost. Now you don’t have to own a Kindle to read Kindle books as the **Kindle app** is free to download for any device you may own: PC, phone or tablet. It is possible to search Kindle books by price, so try a search on **Mathematics books by price from lowest to highest**. If you search on all titles this gives all the free entries which seem to include lots of toddler books and samples. The most relevant results are always worth checking. Another Amazon search for low cost books is a search on **popular Mathematics books, price low to high**. which returns popular Mathematics and Science books for as little as 99p. The free books include some **Open University eBooks** including some titles on Mathematics, see for example **Maths Everywhere**, **Using visualisation in maths teaching****, ****Starting with maths****: Patterns and formulas**, and **Working on your own Mathematics**.

Looking at the free offerings, these include **Mind Hurdles: Mystery Number** – a set of ‘number mysteries’, one or more of which would make a good lesson starter and Henry Ernest Dudeney’s – **Amusements in Mathematics **a puzzle collection (with solutions). The first set of puzzles will offer a trip down memory lane for those who remember money – pre-decimal! There are several categories of puzzles available. Or try **Edwin Abbott’s Flatand **the tale of a two-dimensional world occupied by geometric figures.

There are many other free Maths books online as you will discover with a little searching, see **this collection** for example.

**Colin Foster’s KS3 Instant Maths Ideas** (3 books) are now freely available online; these contain a wealth of ideas to try in the classroom. **Colin Foster **is Associate Professor of Education at the University of Leicester.

*From the Shell Centre for Mathematical Education, you will find some free pdf downloads, such as The Language of Functions and Graphs and Extended Tasks for GCSE Mathematics. *

For GCSE try:

**Complete GCSE Maths Revision text from CLCnet**. Don’t be put off by the 2007 date – this is still useful. The text includes numerous set of questions for each topic by grade with solutions for all the examples.

For Further Mathematics A Level (old specification) (age 16-18) **AQA have provided a set of three textbooks. **(Scroll down to Resources for students).

**AQA-MFP2-TEXTBOOK AQA-MFP3-TEXTBOOK AQA-MFP4-TEXTBOOK**

‘**Street Fighting Mathematics**‘ by Sanjoy Mahajan, with the excellent sub-title ‘The Art of Educated Guessing and Opportunistic Problem Solving’ (note the link on the left to the **free Creative Commons edition** under Essential Info).

Thanks to **Stephen Cavadino**, I came across **Nix the Tricks **by Tina Cardone and many other contributors. This looks like an interesting read – discussing how the use of ‘tricks’ can lead to misconceptions.

**STEM learning** has an extensive library of free resources for Mathematics (and also for Computing, Design and Technology and Science) including textbooks; you can search the collection in various ways, **a search for textbooks for ages 11-18 returns these results. **

You will find a real treasure trove in this collection – **see this separate page**.

The complete **Cockroft Report, Mathematics Counts** is available online. You can use the menu on the left to navigate to the various chapters.

Any discussion on free Maths texts should include of course all the free texts available on the wonderful **CIMT **site (Centre for Innovation in Mathematics Teaching).

**Project Gutenberg **includes numerous Mathematics books, including classics such as **Flatland. **(Mark Twain’s comment on “Classic’ – a book which people praise and don’t read.” always amuses me!)

**CK-12** provides an extensive range of open-source content and technology tools for students and teachers. See for example the **algebra resources here**; click on FlexBooks Textbooks to see the available books. Books such as **CK-12 Algebra – second edition **can be downloaded free in various formats, PDF, mobi and ePub. To download books you will need to sign in (free); you can create an account or sign in with Google, Facebook or Twitter.

You could **even write your own**! If publishing your own Kindle eBook feels a little too much right now – you could try something simpler!
