I know these are little things, but for example...at our school, by the gym there are these flashing boards that show upcoming events...like a digital display board. That board was $3500 (not sure if they did a fundraiser for it, I know I surely wouldn't have contributed to it), not to mention the electricity it costs to run it.
All the flyers that are sent home are always on colored paper, why not white? White is cheaper. Why not send these things over email? The amount of paper sent home is absolutely ridiculous! Instead of giving the kids paper to write on all the time, why don't they use small dry erase boards?
Using the same books for more than 1 year! Better yet, ditch the books altogether. There are hundreds of free online educational sites. Also, if you do opt for using books and they come with a workbook (which at the end of the year, my kids workbooks are literally half unused) then negotiate a better price without the workbooks. OR, print worksheets off of the internet if you're going to be using that much paper anyway.
Put a freeze on travel, materials, supplies, etc unless it is absolutely necessary to carry out the performance of educating students.
Janitorial staff could possibly work part time versus full time? Is it 100% necessary for all rooms to be swept every single night? Could it be every other night temporarily?
I just wonder how many things could be donated each year to a school if parents were asked. Magazine subscriptions, computers, classroom games, books for the library, etc.
