With TI-Nspire™ and TI-Nspire CAS technology, educators and students can see multiple representations of a problem – algebraic, graphical, geometric, numeric and written – on a single screen. Explore individual representations, one at a time, or as many as four all on the same screen.
Choose different split-screen options. Using a drop-down menu, select the number of representations and their arrangement on screen.
Representations can be dynamically linked.
This means that changes made to one representation of a problem are automatically reflected in other representations of the same problem – instantly, in real time, on the same screen. The dynamic linking of multiple representations provides real-time, interactive feedback so students can try different problem-solving techniques.
Research shows that students learn mathematical concepts more readily and with deeper understanding when they learn across different forms of representation. When they are able to see the math in different ways – through multiple representations – they begin to broaden their critical thinking skills and make meaningful connections.
This unique ability to see and explore multiple representations on a single screen is supported by the following applications built into both the TI-Nspire handhelds and TI-Nspire software:
 CALCULATOR supporting algebraic representations
Perform computations. Enter and view expressions, equations and formulas exactly as they appear in math textbooks. Quickly and easily select the proper syntax, symbols and variables from a template that supports standard mathematical notation. Scroll through previous entries to explore outcomes and patterns.
 GRAPHS & GEOMETRY supporting graphical and geometric representations
Graph equations, expressions and other functions. Then make changes to variables to see how the values in dynamically linked tables and equations will also change, in real time. Add labels, rename the axes and include text on the graph's coordinate plane. Construct and explore geometric figures interactively and create animations. Integrate graphing and geometry on the same screen to help reveal connections between concepts in algebra and geometry.
 LISTS & SPREADSHEET supporting numeric and analytical representations
Capture and track the values of a graph and collected data, and observe number patterns. Organize the results of statistical analysis. Experience capabilities similar to using computer spreadsheets: label columns, insert formulas into cells, select individual cells and change their size, and more.
 NOTES supporting written representations
Put the math in writing. Include the word problem with its solutions. Explain problem-solving approaches - right in the handheld or computer software. Question-and-answer templates allow educators to prompt students to document their steps and progress.
