Summary: The author promotes algebraic thinking through the use of technology risk tasks. Not only is this a good read, it offers a template for the use of technology that can signpost both thinking and application to future practice for the reader. In the words of the author\dots\ One of the most important things that I have realised is that one needs to invest time and energy in allowing students to get to grips with the software before they can begin to use it as a mathematical tool. I see this as a transition from pushing physical buttons to pushing mental buttons.
