Fast forward a few decades and I want my kids to do the same. I am not going to try to conjure this up in Excel though. Instead, I made a Mac and iPad app. I spent quite a bit of time letting my kids play with early versions, tweaking things as they uncovered issues that only a kid would think of.
With this version finally out (the app review process is always sooo much fun), MeteorMath will be worked into their daily schooling routine -- hopefully without lessening the enjoyment they've had with it so far.
I'm presently struggling my way through the 13's. There's something about 52, 65, 78, 91 that I'm not "internalizing" quite as quickly as I'd like. The app goes up to 20x20, and I'm going to keep working on getting there.
Check it out and let me know what you (or your kids) think of it.
One last thought: this is the first from-scratch app I've done in quite a while, so I went "all the way": Swift 6, SwiftUI and SwiftData. I've got so many mixed feelings about it all, but it worked, so I can't complain too much.
