Teachers can start by downloading their course roster directly from the Manhattan classroom and importing that file into their favorite spreadsheet program or grade management program. At any time during the course, the teacher can export the grades to a tab-delimited text file and send that file to the Manhattan Grades module. Manhattan distributes the data so that each student sees only his or her grades, plus all other rows of the spreadsheet which do not contain an individual's student's grades. It's simple and effective. Look here for additional information about the Grades module.
Manhattan is a simpler distance learning solution.
