There are no guaranteed apps that are capable of what is required by

You all bring up good points but you have to PICK SOMETHING so if it's not
MS Office, what is it that is editable that is also WYSIWYG on both Mac and
PC that everyone already has and knows how to use?

If not MS Office, then what?

One of the free, cross-platform office app suites might be a better
choice, then at if they don't have it, it is at least free for them to
install. Of course, most of them can open PowerPoint documents anyway,
so they could still do that if they want to. On new-ish Macs, Apple's
Keynote presentation app is free and can open PowerPoint documents
already. Although, any app claiming to be compatible with anything else
isn't always 100% so.

BUT, you are still left with the font problem. I don't think there are
any identical default fronts which are installed on both Windows and
MacOS either, so there's no way around that.

One potential way around all of it would be to use an online office
suite like Google Docs, but they do need to have their computers
connected to the internet (some schools may not do that with their lab
computers so that kids can't muck around in Twitbook or whatever
instead of doing their school work).
