Each bill is about 2-in. x 5-in. in size. All of my bills are kept in two containers purchased from The Dollar Store. I have also tried storing them in pencil boxes (the same ones my students use), but I found that the money would slide around or I would have some bills facing one way and another stack on the end facing a different way. It just bothered me.
After I took a year off to be home with my little girl, I came back to teaching second grade by myself. I wanted NEEDED to use classroom money to keep those second graders motivated to make good choices. My priorities had changed and I just couldn’t dedicate myself to a monthly market financially or professionally. I needed to come up with some free or low-cost rewards that my students would enjoy. So, I created my Classroom Reward Coupons (yep, they’re free on TpT).
Update – Good News! If you’re thinking about using money in your own classroom, you might be interested in this set of editable classroom money.
