Aimed at math teachers and classrooms, the TI-Nspire with Touchpad graphing calculator features the capability to show math problems four ways simultaneously on a single screen: as a graph, table, equation, and a text problem. The latest version has a touchpad keypad that gives the handheld the feel of a laptop, an alpha keyboard for easier text creation, and a scratchpad feature that lets users perform quick calculations and create graphs without opening a new file.
The dynamically linked representations all update each time one part of a problem is changed. This feature enables students to understand relationships among math concepts. Students also can create, save, and edit their work similarly to the file storage of a computer. (Retail approx. $145 — available now.)
