I haven't seen such games, except silly, that do that.
Maybe some other foundational math principles implemented as games.
I love https://www.zachtronics.com/ games, but these games are for 12+ I guess, and even more. Not always about math though.
Adults assume that kids are fine with silly educational tools. While in reality they're boring, because every school implements some sort of cheap flash/html5 games that solve nothing. I want the kiddo to solve hundreds examples in 3D, maybe even in VR, and enjoy that. Instead of 2D browser old-skool tech.
I don't understand why VR is underutilized in education. Where are all the games we're supposed to have to educate children? Imagine how easy it's explain x^3 (like 10^3, 25^3, and so on) in VR?
I am using VR for fitness, and it's been a great success. Lost 17 pounds with 5 more to go for my goal. I am paying $20/month for the app. But I'd be willing to pay for similar math educational app.
