I started off by laminating a few things. I got these posters from WeUseMath.org. And they were free!
I also laminated these guys, which I found on #pinterest (ha!) and typed up myself.

I found these lovelies at the Target dollar stop today. I've seriously spent too much money there this summer! I'm thinking of using them to put supplies in for each group to use with INBs. You can see a glimpse of the border that I put around my whiteboard behind the bins.
I put my new Einstein poster up by 2 others (think I'll call it my Einstein corner) behind another Target find. Although I bought some crates to put the INBs in, I like these holders, too. And they're smaller. I think they win!
