I'm a high school math teacher with 20+ years of experience and have used nearly every graphing calculator model out there since the TI-81. This Casio model wouldn't be my first personal choice or recommendation to families, but it has definite strengths and it's an unbeatable value for the price.Compared to the ubiquitous TI-84, the Casio has better home screen functionality. It reports fractions, simplified roots, special trig ratios, etc. as exact values instead of decimal approximations. You can bring up a fraction template or switch between exact and approximate values with a single button press. The keys are large and have nice action and a sensible layout. The calculator is very powerful and easy to use on the home screen. And - to be fair - that's where students spend much of their time on a calculator in math and science classes. You can also download a free CAS package to provide symbolic solving, simplification, differentiation, etc. for upper-level HS or university courses. That's a tremendous value for the price!However, I've always found Casio's menu system clunky when it comes to graphs, tables, stats calculations, etc. and this model is no exception. The relatively low res screen doesn't do this model any favors for usability either. Anything that's not a home screen calculation seems to take an extra couple keystrokes compared to a TI-84 and/or just be more confusing. To take one example, tables of values are generated within a finite range that can only be modified explicitly. So if you generate a table for a function, you get values for x=-20 to x=20 by default. You can't just scroll up or down to see more values outside that range without trekking back through the menus to the table settings, which are themselves much harder to find than on a TI. This is quite awkward for students that haven't yet developed a sense for what part of the domain they want to examine! Clumsy UI choices like this abound.If money were not a consideration, I'd still hesitantly recommend a TI-84 Plus CE over this model for typical students. The TI is weaker on the home screen, but the higher screen resolution, simpler menus, and wide availability of help/tutorials make it easier for students to use on balance. Now... is a TI-84 Plus CE worth more twice the price of this Casio? Maybe not. If money is tight, this is a terrific choice. It can certainly do everything an 84 can do and more, just maybe with a bit more effort. However, the HP Prime (at the same cost as a TI-84) is a far more powerful and usable calculator than either this Casio or the TI-84 - the Prime is my personal favorite calculator and the model I'd recommend for students pursuing STEM paths that require calculus and post-calculus mathematics.Outside of educational settings, this Casio model would also be a fine budget choice for hobbyists or professionals that might occasionally want graphing, stats, or programming capabilities but that don't need something as full-featured and costly as a Prime or something more specialized like an RPN calculator.Overall, this isn't my favorite graphing calculator for students. But the value for the dollar is unbeatable if you're dedicated or experienced enough to deal with its quirks.
