This page of four credit cards can be copied for a class set. I use credit cards in my class as behavior incentives. When I catch a student doing something exceptional, I sign my name off on a square. Once the credit card is filled up they can redeem it for classroom rewards! Kids love having their very own credit card to make purchases with!
These are "bee" themed, but I have another upload in my store that is editable if you would prefer adding your own classroom theme.
