Can I make changes to the digital slides or add my own slides?
Not at this time, but this functionality is on our road map for future school years. For now, use your teacher tools such as selecting and removing slides using presentation sync and your own outside resources to add or modify a digital lesson.
How can I track student progress over time?
Teachers can track student progress by using the Reporting application. There are two different reports: the Unit Performance Report and Standards Reports. These allow teachers to review performance by unit for assessments, practice, and exit tickets as well as view progress and performance by standards.
