To avoid having money lost or stolen, I use a Power Mechanix 30 drawer organizer. I put each child's name on a drawer. Each morning they have the option of giving me their money for the day. At lunch or snack time, I get it for them. It takes a lot less time and hassle than looking for missing money. The students know that if they don't give me their money I will not be responsible for it. Since it is also understood no one has any reason to be on the teacher's desk, I have no more problems with stolen money.
