**The Texas Instruments TI-Nspire** is a graphing calculator that is designed exclusively for students of any math class. Its technology allows students to see and make connections with up to four problems at a time on one screen.

Bonus: Get the best graphing calculator from Calcustar.com, if you are not interested in Ti-Nspire. The CAS version is better and newer.

These four representations of a problem include algebraic, numeric, graphical and written formats. All these can be viewed and studied in real time. This is an ideal choice for students struggling in math class.

They can learn different types of equations and expressions by watching the practice problems being produced. They can also get an idea about how various concepts are linked. These functions help students sharpen their critical thinking skills because they will be able to actually see mathematical patterns and relationships.

The TI-NSpire graphing calculator contains functionality similar to that of a computer. Students can even create, save, and edit documents. This means that if a user runs out of time when inputting an equation, he/she can save the progress and resume later. For instance, students can study the relationships of rise, run and slopes by using a graph on the TI-NSpire.

This handheld device can be used on all the important high school exams, such as the ACT, PSAT and SAT. Corresponding software can be attained online, along with other applications and packages.

Studies show that the use of apps makes students feel more excited and interested in math! Even students who normally claim to hate math class find that learning can be easy with the TI-NSpire graphing calculator.

What’s more, this hand held device can be used for scientific purposes as well as mathematical! Here are some details about the TI-NSpire:
