I’ve also seen US teachers spending hundreds of dollars out of their own pockets to stock classrooms.
I spent a lot of time in European schools and I’ve never heard of teachers having to stock their own classrooms or fundraise for things like playgrounds, etc.
In Australia, we get a stationery list at the beginning of each year. So many pens, pencils, a set of coloured pencils, this many lined exercise books, a ruler, erasers, an art book, a set of watercolour paint, etc. in some grades the kids (parents) leave these at home and the kid brings what they require when they run out. Other grades, the teacher takes them all and locks them in a cabinet, gives them out when required.
Some schools buy 47 (whatever) copies of Romeo and Juliet, Chemistry 1, To kill a mockingbird, Algebra and Geometry, etc, and loan them to the kids at the start of the year. You break it, you buy it. Other schools get you to buy your own books (they tell you which version of which books, and there are commercial bookstores that sell specifically to the school market), but have a school bookshop so you can sell it back at the end of the year, and buy next year’s books secondhand which another family sold. (Or buy new from bookstores mentioned above if there are no secondhand books available at the school bookstore).
The teachers still have to buy their own equipment: chalk, whiteboard markers, pens and pencils, but the stuff they buy is for their use. Some schools have laptops and smart whiteboards; these are provided by the school.
(My kids only went to public schools, I don’t know how private schools work).
It really doesn’t sound too different, but what where do you get wipes to clean everything the kids get their greasy hands on, paper towels, tissues for all the colds? How do you help the kids who always forgets his pencils or runs out of paper, or didn’t have enough notebooks.
A big expense that took the most personal time was classroom decoration, although maybe that’s more for the little kids. The school provides a concrete box with beige walls and desks. It’s a prison. A hopeless, tedious, boring prison. How can you not have places to highlight their work, education assisting devices, and even try to hold their attention and imagination? Are you really teaching g numbers without a number line, vocabulary without making words visible, geography without a map or globe?
Then the biggest expense my ex had as a teacher was stocking a classroom library. The school won’t pay for that because it’s not a direct part of the curriculum, but how can you not have one? How can you not try to gain the interest of any kid with a chance of reading? How can you not provide a reading opportunity to any kid with spare time or who finishes their work early!
