Accelerate the Understanding Process

The TI-Nspire CX handheld’s innovative capabilities support teaching strategies that research has found accelerate understanding of complex mathematic and scientific concepts.

gen-product-icon-multiple-reps Multiple Representations of expressions in problems are presented simultaneously, enabling students to visualize how algebraic, graphical, geometric, numeric and written forms of those expressions relate to one another.
gen-product-icon-dynamiclinking Dynamic Linking across documents and multiple representations allows students to interact directly with the math by seeing how manipulating one form simultaneously changes all the others.

Make Real-World Connections

Import digital images – including your own photos – and overlay graphs and equations on them to see math and science at work in the physical world.*

*TI-Nspire™ Technology supports images in .jpg, .jpeg, .bmp and .png formats.

Enter Values In Proper Notation

Integrated mathematics templates permit students to enter expressions and see math symbols, formulas and stacked fractions just as they are printed in textbooks and on the board.

The unique Chem Box feature lets students easily input chemical formulas and equations.

Click, Scroll, Create and Save Like a computer

Use intuitive drop-down menus to navigate through the TI-Nspire with Touchpad handheld.

Create documents and pages and save your work as simply as opening, editing and storing files on a computer.
