Cabri Junior, Discovering Interactive Geometry on the TI-83

Abstract

Now dynamic, interactive Geometry is available (free) on the most popular graphing calculator, the TI-83. Its renewed interface makes it is even easier to use than the regular Cabri II on a computer. We will introduce CabriJr main features and show, based on selected examples, how teachers and students are now getting a deeper understanding of geometry on their handheld. (We will also show how CabriJr and Cabri II Plus exchange their files bridging the world of calcs and computers).
