The ATM

In June 2019, the Association of Teachers of Mathematics (ATM) published the Algebradabra! blog as an A5, spiral-bound book. It can be purchased from the ATM website and costs £12 for members of ATM, £16 for non-members. The book comes with a high-definition pdf file of SLIDES showing all the tasks from the book, along with a link for downloading a set of QuickTime movies that support some of the tasks. 

The ATM was established in the UK in 1952 to encourage the teaching and learning of mathematics.
It is a registered charity and has a membership of approximately 3000 individual teachers and other maths educators, as well as schools and other institutions.

The Association offers a number of CDP opportunities that include the annual conference, local branch meetings and regional one-day events. Its journal, Mathematics Teaching, is published five times a year, with articles which reflect on the practice of teaching mathematics from the Foundation Stage to Higher and Further Education. Contributors are encouraged to express their personal views on the teaching and learning of mathematics.

ATM also produces many other resources and publications, including now the Algebradabra book!
