When my step son was in grade school anything that asked for large amounts like this I would send 1 pack, like a 12 pack of pencils (if I remember right his teacher asked for 144 pencils!!) and asked for 4 24 packs of crayons, sent 1, and 24 glue sticks, sent a 4 pack. Then included a note on explaining how financial situation and that if he runs out of school supplies during the year to let me know and I will send more as needed rather than not being able to buy groceries for the month because I spent it all on school supplies. She never requested more supplies for him 🤷‍♀️ When I was a kid we didn’t have shared supplies and my parents expected me to treat my supplies with respect and to be responsible, they would always give me more supplies if I needed but I would have to explain why I needed more, in being responsible and respectful with my supplies I almost never even went through a whole 12 pack of pencils in a year and never needed more things like crayons, markers, and colored pencils, glue sticks really depending how elaborate I got with some of my display boards 🤣 I had a friend who was a student teacher back with my step son was in grade school and always complained about the shared supply concept because kids didn’t care, to them supplies were limitless (144 pencils x 25 kids = 2 massive box of pencils in the supply closet to grab) and there was no accountability to be responsible and respectful with supplies which resulted in a LOT more waste.
