Follow these steps to enter your Marble Roll data and send it to the central database.

You'll enter your row of data into a form, check the data for accuracy, and send it. Then another person will do the same thing. Each person will enter, check, and send data until everyone in the class has submitted their row of data. This can take a long time. So, it might be best to set up a schedule so each person knows when it is his or her turn to work at the computer.
