Over recent years, spreadsheets have been increasingly recognised as having a role in teaching and learning mathematics, but have continued to suffer the limitation of requiring access to computers. In this hands-on workshop, we will use the spreadsheet module on the new Casio fx-9860G graphics calculator to explore the opportunities it offers for both students and teachers. While extensive spreadsheet experience will not be assumed, those familiar with spreadsheets may see this session as a chance to explore how their ideas can be translated to the hand-held context, while spreadsheet beginners are also welcome. No previous experience with this graphics calculator will be assumed.
