I have used the 3 following FTP clients during the past years so here is my feedback:
WinSCP: the one that I currently use. There is a portable version, just one .exe file (and the .ini file for configuration). Don't forget to turn on the "Explorer" interface:
View > Preferences > Environment > Interface > Explorer, which is (IMHO) handier.
Benchmark: it ...
You should checkout Veyon.
It's open source, available for both Windows and Linux, it does more than you need but those extra features are handy and won't cost you anything.
You can simple monitor what the students are doing, but also broadcast your own screen.
Advanced File Renamer
There is no type of renaming that this program cannot do (among other things). It supports anything from layman-friendly patterns, to regular expressions, to full on scripting (hence the "can do everything"). It also has a CLI, for the really advanced uses.

Both are free AND ad-free when I last used them a year or so ago.
If trial software is acceptable then Casio has emulators for their scientific calculators that supports all features in the real calculator including fractions. You can download from here and use it for 90 days
There are also portable Casio emulators that are shared across many math forums and requires no activation but I think they're just patched versions ...
Precise Calculator can do that
Precise Calculator has arbitrary precision and can calculate with complex numbers, fractions, vectors and matrices. Has more than 150 mathematical functions and statistical functions and is programmable (if, goto, print, return, for).
If you don't mind the lack of a built-in graphical interface and you're OK with "computerish" notation, a great completely free option is the Python programming language. You don't have to learn any programming per se to use the interactive interpreter as a scientific calculator with fraction support. You do have to import various modules that are included ...
