Texas Instruments TI-NSpire Math and Science Handheld Graphing Calculator(Swap Keypad)

TI takes mathematics instruction to a whole new level with the TI-Nspire CAS calculator. A large LCD screen makes it easy to see equations and graphs, the split screen mode lets you view your data in multiple formats at once. TI has also updated the operating system and added new functions to make the Nspire CAS both more powerful and easier to use than any of its predecessors.

It also works with various add-ons and software programs. The Connect-to-Class application lets the teacher connect to the calculator through a USB hub to transfer files to students so everyone starts the lesson from the same place. It also allows the calculators to be upgraded as new functionality is available. The Vernier Go! Motion and Easy Temp/Go! Temp sensors can be plugged into the calculator for data gathering applications.
