First Steps with TI-Nspire

About this document

This document includes seven introductory tutorials to take new users through many key features of TI-Nspire™ maths and science learning technology. This technology includes both handhelds and computer software, providing teachers the flexibility to meet different classroom needs. However, the primary focus of these tutorials is the handheld device. All activities are equally applicable to the computer software but screen shots and key presses relate to the handheld.

About the tutorials

The tutorials are designed to be worked through in order, with later ones building on skills covered earlier. The first time you meet a new technique, there are very detailed instructions about which keys to press – but, as you would expect, the amount of detail is reduced when the technique is used subsequently.

In an Appendix you will find an example that links together several of the applications introduced separately in the tutorials. As well as enabling you to revisit many of the techniques you met earlier, it provides an example of the use of “multiple representations” of mathematical concepts.

References

In the tutorials you will find occasional references to documents that are supplied in electronic form with your TI-Nspire handheld.

They are also available from http://education.ti.com/guides, choose TI-Nspire technology.
