When I was teaching, we developed our team lists for supplies carefully, but basically, it included notebooks, folders, writing implements, colored pencils. The school had lined paper, pencils, some pens, paper for the printer in my room. Many kids had their own mini staplers, sticky notes, other art type stuff for projects. I had lots of this kind of stuff, too, that was supplied by the school. Most of the issues I had were when I was doing a "hands on" part of a writing unit, where kids often did presentations. Some would need to buy a heavy 3 sided poster board or other tool such as that (we had the regular thin type posters at school) and parents would just not take their kids to buy that. If I saw their was a financial issue (easy when you work with the same group for 2 years), I bought it for them, but often times they repaid me by doing some work for me (cleaning, arranging stuff in the room).
I had a huge classroom library for independent reading, which was a requirement. Sometimes, though, kids had their own books, which were bought or from the library. This was right before Kindles, etc. I also had a few claculators, a jar of scissors, rulers, erasers, crayons, and markers in my room.
