I don't have kids, but I don't remember learning any of these things anymore then I remember learning to dress myself or how to eat, they were just part of life. I know I was cooking at an age young enough I had to pull a chair up to the stove to stand at it, so I guess pretty young, and by 3rd or 4th grade I was occasionally tasked with making dinner for the whole family. At 11 my mom stopped doing any of my laundry, but she didn't have to teach me how to do it, I already knew from having been expected to help out countless times previously. My weekly chores in elementary school consisted of a rotation (between myself and my brother, each chore for a few months then we'd switch) of vacuuming, dusting, cleaning the bathroom, mopping the kitchen floor, etc. We were expected to shovel the side walks when it showed and rake the leaves int eh autumn, along side my dad, for as long as I can remember. I don't know when I learned to sew but I was making Barbie clothes as a kid and I grew out of Barbie by 4th grade.
I started getting an allowance in first grade and was expected to budget it myself for things I wanted. I only got raises if I asked for them and could demonstrate why I deserved a raise. It started at 50 cents a week in first grade and was up to $25 by 12th grade; my brother never made it over $18 a week.
My dad, a former Eagle Scout instilled in my brother and I a knowledge of basic foliage identification and insisted we could start a fire with no paper and only one match at a very young age. Weird skills to insist your NYC kids know, but then again those were fun things to learn so no harm, no foul.
By the time I was in high school my mom had moved out and my brother was off to college, so it was just me and my dad. He would task me with writing any checks (and balancing the register), etc I needed for school stuff and he would just sign them. Because my grandparents had set up a savings trust for me as an infant my dad had been filing taxes for me annually which he always had me sign myself, but once I had an after school job he made me do my own (which he sent to his accountant to check).
I learned electrical in elementary school science class (simple circuits, etc) and since my parents always did their own minor electrical work around the house the lessons easily stuck.
I went to high school in a different county which required me taking the subway and using buses and/or the railroad, so being able to read a map and navigate public transportation alone well before then was a must.
I'm very glad I did learn all these things although in someways it was a social hindrance in that I had (and to be honest sometimes still do) very little patience with people who couldn't. Knowing how to make basic food, or do laundry, read a map, or change a light switch were just things I expected everyone to know how to do as a matter of course.
