I have read this looong thread and have a quick question. My DD is taking the EXPLORE on January 24th. I found the list of prohibited calculators but there are so many choices. Does anyone have a calculator they can recommend a to me? I'm looking for the exact name, model number so I don't get the wrong one. My DD is 9 and in 4th grade. I would like the calculator to last her a few years but don't want to spend a lot of $$$$.

Thanks so much!
