Inexperienced users of graphics
calculators frequently expect that

their main
advantage involves drawing and using graphs of functions.

In contrast, this is a hands-on
workshop to explore some of the ways

in which a
graphics calculator might support teaching and learning

matrices,
sequences and series, but with only limited emphasis on

graphical
representations. We will use the Casio fx-9860G graphics

calculator
to consider the ways in which sequences and matrices are

represented
on the calculator and can be manipulated to support

mathematical
thinking. No previous experience with this calculator

will be assumed.
