(Texas Instruments)
Graphing Calculator (TI-84 PLUS)
An enhanced version of the TI-83 Plus, the new TI-84 Plus offers a built-in USB port, 3x the memory of the TI-83 Plus, many preloaded Apps, an improved display, and more!
Because the new TI-84 Plus is 100% keystroke-for-keystroke compatible with the TI-83 Plus, integrating it into your classroom will be easy!
With the TI-84 Plus, all students can now share their work by connecting their TI-84 Plus to any TI presentation tools for the whole class to see, fostering a collaborative learning environment.
Plus, a built-in USB port makes data transfer to your computer and between handhelds easier than ever.
