I have never heard of anything this bad in my area and I know teachers in a lot of area school districts.
My district is not a wealthy district and my school is a Title I school.
We are given a curriculum roadmap that has a lot of suggested activities and labs and graphic organizers (some units are better stocked with suggestions than others), but we have complete freedom in how we teach it. At our school, none of us on the chemistry team use the horrible textbook. We do have to try to keep on pace with the curriculum roadmap because there are district-wide assessments.
I have spent a lot of my own money on supplies for experiments, but these are experiments that I chose. The money has generally been for food-based experiments, like when I used Oreo Thins, regular, and Double Stuffs for isotopes and when I used S'mores to introduce stoichiometry. The Oreo lab ended up costing about $50 and I think the S'mores lab was about the same price (that was longer ago).
I have also spent a ton of money on dry erase markers, composition notebooks, golf pencils (a lot cheaper than regular pencils), and tape. Every 6-9 weeks I have to order a class set of dry erase markers (30), golf pencils (box of 100), and tape (6 rolls). I bought 50 composition notebooks for my students this year and I have only 5 left. At least this year I knew what I was in for and bought them when they were $0.50. Last year was my first year to do interactive notebooks and I bought just 25 at the sale price and paid a full dollar for all of the rest of the notebooks that I purchased for my students. The notebooks are graded, so they have to be supplied if the students don't have them.
