A comprehensive set of materials in book form written by Peter McIntyre for the TI-84 (84, 84CE) and for the Casio 9860 (9860, CG20, CG50) families of graphics calculators, which covers most models currently in use in schools other than the TI-nSpire/Casio ClassPad.
The materials range from mostly how to do various Maths operations on your calculator in a mathematical context to more-extensive notes. All are illustrated with examples and calculator screen shots. All topics have exercises and/or activities with full solutions.
The aim is to make life easier for teachers and students to use the calculator for Maths and to appreciate its full power.
