Spent an hour this morning with the VICE C64 emulator (https://vice-emu.sourceforge.io) running full screen on my Mac, a scan of the Commodore 64 Users Guide open on my iPad, and the 11yo at the keyboard.
I'd read passages and dictate code from the book, and he'd type it in and see what happens.
He had fun for a while, but of course the examples are so.... basic (pun!) that by modern standards they just don't excite much, but hey, he still learned a bit and enjoyed it until the typing got "too long."
