Tutorial 1

TI-Nspire Documents

This first tutorial introduces some of the key features of TI-Nspire™ learning technology, in particular the structure of TI-Nspire documents, with different applications operating on different pages. The various menus are introduced, as well as creating and navigating around documents. The tutorial assumes that you are using the TI-Nspire handheld device and the tutorial begins by drawing a comparison between this and other types of technology.

Is it a calculator? Is it a computer? ….It’s a handheld device!

Pick up the TI-Nspire handheld device and, if you are used to using a calculator, particularly

a Texas Instruments TI-83 or TI-84 graphics calculator, you are likely to feel a certain reassuring familiarity: there’s a screen and a keyboard laid out in a fairly familiar way. As with many calculators the on/off switch is in the top right corner. So press c to switch on.

Nothing on the screen?

See Getting Started with the TI-Nspire Handheld, Recharging the Handheld

Please don’t worry about what’s on the screen for the moment, but think about how to switch it off. The c key has “off” written in light blue above it so that’s the one to use after pressing the blue key marked /.

But just a minute, it was a key marked 2nd that you used on the calculators, and the change to the use of a ctrl key is quite significant. The designers at TI have moved to making this device much more like a computer and it has a ctrl key, /, and also a shift key g. Many of the main keys on the handheld have second functions written in blue above the key and these are activated using the ctrl key. Notice for example q, p and h. The ctrl key can be used in conjunction with the alphabetic keys to create keyboard shortcuts just as you are used to doing on a computer. For example, you can copy and paste using /C and /V. There’s also that most useful keyboard shortcut for undoing a previous action, /Z, which can also be activated by pressing /d(ª). (See Getting Started guide, Using Keyboard Shortcuts for a full list).

Memory

Just like a computer, documents can be stored on the TI-Nspire CX handheld – The TI-Nspire™ CX handheld comes equipped with 192 MB of memory Of the total memory, 128 MB is dedicated to document storage. As documents are created and stored they take up space on the handheld’s memory so you may find that every now and again you need to free space on memory after long-term use. If there isn’t enough memory on the handheld, you can do one of the following:

•Back up documents and folders to a computer or another TI-Nspire CX

•Delete documents and folders you no longer use

•Reset the memory, which deletes all files and folders on the handheld
