Casio has a great web site with directions for their calculators as does
Texas instruments.
Steck Vaughn has published a booklet called mathematics calcultor.
ISBN 0-7398-4668-X
The Casios come with a little directions booklet that helps also.
Students mostly need practice.

Does anyone have student directions for using the Casio for GED? Some
students are confused and making GED studies difficult.

adult ed folks would be needing thousands of them, he was surprised.
But never got back to me about bulk orders. I waited until a few months
ago and repeated the exercise--with the same results. Finally I called
GEDTS and ordered 10 of them.

the calculator off and on for about a month now, developing some
volunteer tutor training. Unlike the other Casio units, or the TI
units, there are no handy classroom instructional materials to build on
or to use as handouts. The only directions are contained in a fold out
piece of paper in the unit and I found it less friendly than the TI
Explorer, which I've used with adult ed students.
