Interactive mathematics on the ClassPad 300

This paper describes some of the fresh opportunities for learning mathematics that have become available with an interactive hand-held device, the Casio ClassPad 300. Some of the different ways in which students can be engaged interactively in mathematical work are described and illustrated. These include interactions on a touch-sensitive screen via a stylus, drag-and-drop interactions between applications, the use of two windows simultaneously, the use of measurement bars, the deployment of dynamic links between windows and the concept of an eActivity, designed for organizing student interactions for a particular purpose. It is argued that interactions of these kinds have considerable potential for learning mathematics.
