This scavenger hunt is a great introduction to the TI-NSpire CX handheld. I've used it with students (7th and 8th graders) and in teacher workshops. Hand them an NSpire CX and this three-page handout and they'll be ready to do basic calculations, work with fractions and graph functions in no time. Let them work at their own pace and be there to help if they can't find the correct keys. It was written for OS 4.0, but you can use it with other OSs. A color-coded answer key is included.
