The first website I'm featuring is Corbettmaths.com. You're probably familiar with this website, but have you explored it lately? Do you know everything it has to offer...?

The writer of Corbettmaths is John Corbett, a maths teacher based in Somerset who shares an astonishing volume of resources. His website has been around for quite a while - it was established in 2011, and over the years has accumulated thousands of free resources which are now used by teachers all over the world.

**Quizzes**

I thought I knew this website pretty well but when I was exploring it in preparation for this presentation, I found some stuff that I'd not seen before. For example, the Class Quizzes section has caught my attention. This is a new section of the website that is still being developed, but there are enough resources here to get started.

The idea is that these quizzes are given to GCSE classes to help them memorise key facts, formulae and processes. Students write 1 - 10 in their books and the teacher reads out the questions. I really like this idea and plan to start using this with my Year 11s from January. I think my students may also find these useful for self-quizzing at home during the final countdown to their GCSE exams.

**Condundrums**

John writes great maths puzzles and shares them in the Conundrums section of his website. These problems are challenging yet accessible.

**5-a-day**

John's 5-a-day resources are widely used. Each sheet features five quick questions from a mixture of topics. This allows students to revisit previously taught topics on a regular basis ('interleaving').

The range of resources here is impressive - there's a whole year's worth of 5-a-days for new GCSE at five different difficulty levels: numeracy, foundation, foundation plus, higher and higher plus. There's also a set of 5-a-days for A level (Edexcel Core 1) and later this year a collection of primary 5-a-days will be added to the website.

Some teachers use these resources as daily lesson starters, others have a corridor display where students can pick up their 5-a-days. John has blogged about the various approaches here.

**Videos and Worksheets**

John's videos and practice questions are a big part of the website. I find these particularly useful if I have a student who has missed a lesson or struggled with a homework - I email them a link to a Corbettmaths video (I like it that these can be accessed without the need for a login). Each video comes with a booklet of exam style questions and a textbook exercise. John has a blog post about how to use his videos and practice questions here.

**Revision Cards**

Higher and Foundation GCSE revision cards are now available to buy from Corbettmaths.com. They cost £8.99 per pack (discounts are available for bulk orders). This is a good use of pupil premium budget. These have been very well received by teachers on Twitter. They have the unique feature of a QR code on the back which takes students directly to a video for each topic.

If you didn't already know all the features of Corbettmaths.com then do explore. Hats off to John Corbett, a hard working teacher making our lives easier and helping students over the world.
