Subject: Re: Graphing Calculator Courses

I have been tutoring algebra I and II for several years after my
retiremant.  I bought a TI-82 and mastered it only to find out that
the local school used a CASIO.  I was also volunteer tutoring at the
local high school so set about learning the CASIO graphing calculator.
I made a few view graphs for my own use and decided to market these. 
I then found that the state was mostly using the TI-83 so I went to
work and made vu-graphs for the TI-83.  I sold a few, but the cost to
make was a little high and I didn't sell too many.

I then took the TI-83 charts and reduced them to fit on 4 by 6 index
cards and then bound them with a plastic comb.  Since then I have sold
about 110 of these booklets and have not had any negative feedback on
them but have had quite a few positive feedback's.  

If you are interested, email me at the above address.   I also sell
them on Ebay. Here is the contents of the cards:
