The rantings of a teacher who retired from the classroom but not from education.
I can't imagine having to learn a new calculator. Don't all the text books in New York come with graphig calculator actiivties for the TI? Ours do. I have never seen instructions for any other type of calcuator. Two years ago our school got a grant to purchase 1200 TI graphing calculators. We check them out to students just like a textbook. It is nice that they all have the same calcualtor.Good luck with the Casio.
We have 5000 kids in our building so 1200 wouldn't do us much good.
I have used TI since I started teaching about 10 years ago but changed school this year and my new school use casio. Was tricky at the start but once I got past my early frustration it wasnt that hard. To learn your 2nd calculator is only a small fraction of the work you needed to learn the first.
