Hmm… speaking of the 90’s, though it’s on the tail end of it:

Mia Mouse/Mia’s Big Adventure Collection was something I recall playing as a kid.

I definitely think I was much younger than 7 though, I’d been playing RuneScape for close to 3 years by the time I was 7. Mia’s is probably still appropriate & engaging enough for that age though.

I think I’m specifically remembering Mia Math, but it looks like there’s Math/Science/Reading/Language, seems to be marketed for education.
