    This is the season to treat the class to some nifty arithmetricks. Here's a fun one to provide some calculation practice. Choose any 3 digit number with the same single digits, (except for 0). Add the digits. With the original 3 digit number as the dividend, divide by the sum. The result is always 37.

    Example:

    333 3+3+3=9 333/9=37

    Any other ideas?
