For teachers of AQA GCSE Maths, the (WordPress) blog Teaching AQA Maths 2010, published by the Maths team at Longman has some useful resources. The post linked to here has a free practice paper and mark scheme for Unit 1 higher for example. Relevant news is posted. Definitely worth keeping an eye on. An early post on the blog on the book ‘Street Fighting Mathematics’ by Sanjoy Mahajan includes a link for a free pdf download of the book.
