The graphing calculator enables students to view mathematics visually and allows them to see patterns that are more difficult to detect when done by hand. In some classrooms they use the TI-Navigator system which enables the students to network their graphing calculators wirelessly to the classroom computer thus enabling a more dynamic interaction between all members of the class. In some classrooms you will see students using a wonderful geometry program called Geometer's Sketchpad, which enables students to manipulate and measure geometric shapes on the screen in order to detect mathematical patterns.
