TI-Nspires are amazing calculators. There are so many features, don’t try to learn them all at once. First of all, get the teacher software! I can’t live without it. In my district, even the students have the software available on their laptops. It’s wonderful.
How do you get started? The first thing I learned was go to the HOME SCREEN and choose NEW DOCUMENT. If there is a screen that asks if you want to save, say no. Now choose what you want to do. If you are learning, you will only choose graph or calculator. This is what I still choose most of the time!
The calculator screen is easy to use. If you are looking for something specific it is probably here: (see below) I used this button to type in a cube root as seen in the next pic.
Let’s say you now want to graph something. You have a choice. Start completely over and go to the home button and go through the same steps explained above, or add a page to your document. Let’s add a page. Simply click CTRL (blue button) +Page (doc button below home.)
Choose Graph! Now you can type an equation. The x button is one of the white alphabet buttons at the bottom of the calculator. Hit enter when you are ready to graph. To graph a second equation, click the tab button and type in a new graph… or to change the first equation, after clicking tab, up arrow to the original equation. If you know this much, you are ready to use the calculator. The only other things that are nice to know at this stage is that ctrl t will pull up a table (and ctrl t will take the table off).
AND the menu button has many things that will help you. I suggest clicking the menu button and checking it out! I use #4 and #6 daily. #6 is where intersections and zeros are and #4 of course helps you change the window settings like on the 84+.
My goal was to help you get started. If you will start using these features and become very familiar with the calculator, you will discover new things on your own. Your students will also help you discover things. The main thing is to get started! Don’t let those calculators just sit. They are really awesome and helpful!
