I have decided to keep track of what I spend on supplies (and where I put them) for this school year. Just getting ready for this year I have spent $170 for my students. I am still looking for notebook paper, copy paper (at a price less than $30 a case), and copies of a few things (to make posters for my room).
And this is really cutting back for me.
