George Watson’s College is a mixed independent school and I have been using the TI-Nspire Navigatorsince October 2008 with most of my classes. In this lesson I used the File transfer, Screen Capture and Quick Poll features.
The students had the opportunity to explore a numerical sequence displayed to them as a graph. This forced them to look at the trends in the terms of the sequence and not just the numbers. The sharing of thoughts at the ‘half-way’ stage led in several cases of students checking some of the declarations that had been made by their peers and revising their own statements in response.
