This classroom Excel bank is perfect for deposits and withdrawals of classroom currency in a classroom economy. I have used this for years with my students. The students themselves, in fact, in the role of the banker have taken up doing the bank management themselves. This gives them exposure to using electronic spreadsheets as well as keeps track of classroom money in a way that is more relevant to the modern world.
The teacher and the students simply input their money into the spreadsheet and it calculates monthly and total amounts in on the sheet. The student totals are displayed on the first page of the bank.
