Same for me, except I was forty-something. I captured something of the experience after stumbling on the “duncan beach ball puzzle”. After memorizing the moves for the cube I read a lot about how a person could solve the puzzle (and ones like it) from scratch. So then I went looking for other permutation puzzles to try the technique. The technique was basically do some sequence of moves, then one move, then undo the sequence. After that notice what 2 or 3 elements swapped places in the permutation. Everything else remains the same. This was easy enough with the beach ball and the classic 15 puzzle. Give it a try!

Pebble Power Place Value sounds like a good name for a math game. Unfortunately, the generated game is incomprehensible. What's the "starting space"? The game board is described as having (2?) spaces marked for ones and tens, then later it has two sections. So I think two spaces/sections based on the description. Or maybe it has 20 spaces in two sections?

The article's defense seems to be that it is just a draft. I tried to get past a draft by asking for explanations of various terms and how play proceeds. No luck. If I hadn't already taught place value to first-graders, I'm not sure I'd have much luck figuring out how to have the AI help me improve the game. If I hadn't yet learned place value because I'm still in first grade and haven't worked with larger numbers yet, I'm sure I would not have much luck collaborating on game design. Also... it is a bit of a reach to assume a first-grader would have the written language skills to pull off collaborating in this fashion.

As a first-grader, I would be able to ask a grown-up if they know of any math games that would help me understand place-value. They might hand me an iPad chock-full of various math games for a little personalized learning. They might also point me to the bin of math games on the shelf, where I could pick out one of a few games on place-value. If I didn't understand the games, I might again ask a grown-up for an explanation, and they would probably direct me to a fellow student who knows the games. (allowing the fellow student the opportunity to flex, expand their understanding of place-value by teaching what they know, and leaving the grown-up free to teach other students how to add single digit numbers)

There are loads of web-sites curated with math games. There are loads of publications targeted at math teachers that include legit math games designed by people with extensive understanding of the difficulties in learning and teaching math.

I don't get how AI finally brings us personalized learning. I guarantee you that first-grade teachers are expected to provide personalized learning for their students, and actually do this all across the world on a daily basis — all with out the support of AI. I really don't see how an AI Tutor helps. It's pretty easy to imagine how it hurts.
