I have no issue with "life preparing" skills, but reading, writing, math skills, which are life prepping do not happen in nursery school. They happen in elementary school, unless you went to a way more advanced system than I did. Learning nursery songs are good things for toddlers as it gets them intellectually stimulated. Stimulation is a fine aspiration. I just hate to see too much emphasis placed on that which doesn't relate to life preparation.
...Apparently I, my kids and literally thousands of others did....I don't know how common or uncommon it is that kids read, write, add and subtract by kindergarten, but I think
by kindergarten, kids are reading, writing, adding and subtracting. I went to a
Montessori school for nursery school and Maret (see the post with the video) for K through 4th grades. My kids followed the same pattern. My kids were reading by the time they were four years old, but admittedly their reading vocabulary was quite small, but they could handle simple words and stories like those in the Dick and Jane books.
I remember the two ladies who worked for my parents and my nanny playing checkers and teaching me how to count to twelve and teaching me how to play checkers. After that, they taught me things like:
Anecdotal Digression...read it or don't...
"When Nana jumps Miss Madeline's checker, Nana takes away one checker and Miss Madeline has 11 checkers," We would say that aloud each time one of them got "jumped" and I would count down. Then Nana would say, "When Nana gets a checker to the other side of the board, you put a checker on top and the checker becomes a queen. A queen is two checkers, and one and one is two."
When Nana got her next queen, she would laugh and we'd together say, "When Nana gets a checker to the other side of the board, you put a checker on top and the checker becomes a queen. A queen is two checkers, and one and one is two. And two and two is four." (To this day, I don't know if Miss Madeline just sucked at checkers or whether they were doing that on purpose. I just know Miss Madeline never won, at least not when I was around. LOL)
That turned into 12 minus 1 is 11, which later evolved into 12 minus 2 is 10, 1 and 1 is 2, a 2 checker queen and another 2 checker king is 4 checkers, and so on. (When I played, my checker got "kinged." )
I also remember going through tons of paper as writing down how many checkers were given and taken away using hash marks. I did the same thing with my kids and they went through tons of paper too. LOL. Does that count as adding and subtracting to you?
We did other stuff like "if Nana gives you five M&Ms and you eat two, how many are left?" I'd have to count them to tell. I also remember quite vividly "giving means adding and taking away means subtracting" and "the cross means give and give means add; the bar means minus and that means take away." We would "sing song" stuff like that, and I'd drive the maid nuts running around the house counting stuff like books, or my own, Daddy's and Mother's shoes and sorts of stuff and "giving and taking away," which, when I was done left all sorts of stuff all over the house. I'd take away books from the shelf and "give" them to the shoe racks, "give" shoes to the bookshelf, or whatever.
(I also "gave" M&Ms to some of my parents' shoes. They didn't like it when I "gave" M&Ms or other chocolates to house shoes that had cloth interiors, so once my naptime began, Miss Helen had to check the shoes I didn't move as well as returning the ones I did to where they belonged.)
I don't recall my kids as writing actual numbers before kindergarten, and I can't say when I first wrote numbers. (I haven't thought of that stuff in years, decades. Boy, those were the days.)
As to how common it is that parents and/or other people who care for small children do the same things as I, my folks and the other adults in my life when I and my kids were young, I cannot say. I do not have any recollection of whether other folks' kids were reading, adding and subtracting by four and five years of age.
If you want to make the point that it was I and my parents, nanny and cook who taught me to read, write and add rather than the preschool, well, okay, but that seems like splitting hairs to me. I would say that I and they were complementing what the preschool was doing. Did I or my kids read books like Dick and Jane alone during nursery school? No, definitely not. I read them to my parents as I sat in their lap and my kids did the same with me and their mother.
