Yes! Students do not have to finish an assignment on the CommonLit digital platform in one sitting. As long as the student clicks the Save and Next button at the bottom of the question after selecting or writing each of their answers, their progress will be saved.
The next time a student logs into their CommonLit account, they will still see the assignment on the My Assignments page under the "Assignments to Do" section. They will just need to click the Resume Assignment button, and then they can pick up where they last left off.
