Using add ons is a great tool to distribute class materials to students. Often times students tend to lose important handouts. This tool allows the students to go back and print the handouts at anytime. It can also serve a a great source of review material before a big exam.Using an add on can help the students to stay organized and keep track of materials distributed by the teacher.I could use Google sheets to create folders for each student in the class. I could also use it to organize class lists, rosters, and data more efficiently.
