I recently gave a talk on current digital technology that can enhance the teaching and learning of mathematics. The title of the talk was "Isn't It Great to Be Alive" which is a reference to an email I received in 2000 in which the author made this statement in reference to how graphics calculators were transforming the teaching of senior Mathematics at that time. I feel the same about the digital technology available today.
I used an IWB (a Promethean ActivBoard) with the talk and have put the accompanying flipchart into the Public folder in my Dropbox. I also uploaded a .pdf version for those that don't have the ActivInspire. It has all the pages but is missing the wonderful interactivity,
I also gave a talk on My All-Time Favourite Middle School Maths Activities. The flipchart, pdf and associated documents from this talk are also available from my Dropbox.
