Telling the whole of the maths story:

how can we keep the plot with graphics calculators?

In this presentation, I wish to make two points and to illustrate them with two examples.  The first point is that new technology is providing us with wonderful new opportunities to improve the teaching and learning of mathematics.  There are opportunities at every year level and through every facility on the new calculators: the home screen, graphing, statistics, programming and, on newer models, symbolic manipulation for algebra. My two examples illustrate simple activities that provide greatly enhanced learning opportunities. Activities like these are now commonplace amongst teachers using graphics calculators, but it is useful to consider what makes them significant  

On the other hand, I see that the major issue for the profession as graphics calculators become widespread is to prevent Mathematics becoming too empirical.  Leading mathematics teachers will have to guard against a tendency towards too much data collection (whether from real situations or from number patterns) and insufficient analysis and reasoning.  How empirical is too empirical is of course a matter of debate In the final section, I will invite you to respond to the dilemmas that face us.
