ask her teacher which one. my son had a less expensive but non-standard casio. the teacher was up front about the fact that she would not be able to help him as much as she was not familiar with the model calculator he had. through the generosity of a MRF member we acquired a TI-83 which he is still using though this year's teacher specified a TI-84. i figured there couldn't have been that much of a change to warrant a new one.
