Back when I was in school we had a schedule, for the semester. That worked perfectly well for me and my parents. Our kitchen had a pin board with these schedules pinned to it. After a month or so we all had a new schedule internalized anyway. As for food, we had a cafeteria which served warm meals, usually at least two different options, and various other things like sandwiches, along with two "kiosks" where the janitors's wives sold some more snacks and sandwiches. And there was a supermarket across the street. I never had a packed lunch, ever, simply because there was no need for it. If I really hated the hot meals of the day, I would get a sandwich. We kids didn't really keep to the schedules anyway, we sometimes went early or stayed late to make use of the table tennis, foosball (or "kicker" as it's called in Germany) or billard tables, or play board games (our school had a sizable collection of these), or play soccer (or "football" as it is called correctly) outside on the school's fields. Mom's only order was to call her (from a pay phone inside the school) if we stayed longer than 1h, so she didn't need to worry (dad was at work). Pickups weren't a problem in this system, as we would always take the public bus or bike when it was warm enough. Our school had something like 1200-1500 students, and about only 30-50 were dropped off and picked up by parents regularly, simply because they lived in some tiny villages somewhere with shitty bus service.

Homework and test prep was supposed to be managed by the students, not their parents, anyway, but most classes had just printed exercises and/or a sheet of what to expect in tests, so parents could always just check that. Test were also in about the same weeks of every semester, so my parents might not have known the exact dates unless they asked and I told them, but they knew that tests were happening. My parents kept interest, asked me how it was going regularly, if I needed help with something, when the tests are and what my results were, and so on. I think so it makes a big difference in the kid's experience if the parent asks them, or if the parent essentially goes over their head and consults some online resource.

I personally was too proud to want help with school work from my parents from an early age on, and even felt that it only slowed me down; I wanted to be outside with my friends not slowly working through the homework as a team exercise. My grades were good, so my parents let me do my stuff. My sisters (they are twins) needed some help in some areas (they are very likely partially dyslexic), and got it.

Should the grades of a student change abruptly for the worse or remain at a low level, teachers would just call up parents and discuss the situation and suggest ways to improve, and the semester reports had to be signed by a parent anyway, and that signature had to be presented at school.

This was mid to late 90s by the way, my mid and "high" school time.
In elementary school my parents were still more hands-on, of course.

I too find "digital child managing systems" rather dystopian, enabling parents to micro-manage their kids even more, which I am convinced is not good for the kid's overall development. There has to be a balance between the parents need to care for a kid (and the care a kid actually needs, of course) and letting the kid grow up, and I feel such systems push that balance too much away from teaching kids self-reliance and let them make minor "educational" mistakes on their own.

Then again, I of course realize that each kid has it's own needs, and some need a fair bit of micro-management at times.

>what to dress them in

May I ask, how old are your kids?
Sounds like they are still young, if you dress them?
Then of course, more micro-managing makes more sense.
The younger the more care kids need.
