On my honeymoon, yes it's scary, I created some rules for my Kipp Kash banking system. I tried to think of any potential difficulties we might run into and charted them as banking rules. Also, I listed any way a student can make a deposit or a withdrawal from their bank account.
I just posted it up in my classroom today (sorry I didn't take a picture!) so it will help everyone have a clear idea of the rules for Kipp Kash management!!
