A graphics calculator provides students with new opportunities for learning important mathematical ideas, in addition to providing a means of undertaking mathematical computations. In this hands-on workshop, we will focus on the first of these two opportunities, those concerned with the learning of mathematical concepts. We will use the new Casio fx-9860G graphics calculator to explore several key areas of introductory calculus first encountered in the senior secondary school, including the concepts of derivatives, integrals, limits, continuity and asymptotic behaviour, to illustrate important principles about learning mathematical ideas with the assistance of technology. Previous experience with this particular calculator will not be assumed.
