One of my past PMs has two primary school kids that they do an extremely less structured version of this for, including some equivalent of story points and a kanban board that they keep up to date with larger tasks (so "eat lunch" is not a WIP ticket).
She says it's been helpful with teaching them how to get better at correctly estimating progress on stuff like summer break homework, studying for upcoming exams and also remembering what day the exam is on, reducing procrastination - at first the "story points" equivalent was wildly variable ranges, but started to get more accurate over time, being able to gauge what was a harder task than an easier task, for example if weaker on maths they aren't embarassed to outright say that and allocate more points/time toward their maths exam revision and dedicate less time to an essay due on the same week.
When writing an essay or studying for a concept they use the ticket/issue comment section to toss in their drafts, links to stuff they find that might be useful later, links to helpful YT/khanacademy videos, and it seems like an organiser of sorts, and the next day can just pick it up from there.
I was really weirded out at first but it didn't seem too absurd after knowing more about it and that it isn't just dinner standup - this is really clearly not making your kids send you an Outlook meeting request to speak to you, but more akin to keeping a journal or todo list, though I think it's going to be moved off Jira soon given the "everything cloud" push and that the $10 10-user licences no longer exist.
