What do I need?

My darling sister read my post about a lack of resources and asked "what do I need?" That got me thinking...what do I ACTUALLY need? As of now, I'm good on the everyday supplies...crayons, pencils, markers, glue, etc. What my classroom REALLY needs is more children's books. Any age really, since I have beginning kindergarten level readers and ready for third grade level readers...I just need more! I did score two huge lots of books from Ebay, obviously retired teacher's old books. They make up the majority of my classroom library right now. I only have one tub of nonfiction books, which is pretty sad. If anyone knows of good sales going on or can find a good deal...let me know and I will reimburse you or come running myself! :)
