Very last minute, I was hired as a second grade teacher at a charter school in Detroit. I'm so excited for the job, but I'm starting from scratch with supplies. Luckily, the school is paying for student supplies and I will try to hit any remaining sales for community supplies. But my classroom library is severely lacking. Besides trying garage sales, where else can I look for inexpensive books?? I also want to get the basics like classroom mailboxes and a sturdy easel. Any ideas? Thanks for the help!
