Can the PDFs of the PowerPoints be converted into slide decks or PowerPoints?

Due to copyright requirements, the PDFs cannot be turned into editable slide decks or PowerPoints. However, teachers can download the PowerPoints to their computers. The PDF files can then be opened with a PDF viewer and advanced with a clicker. This allows teachers to circulate the room while delivering instruction with the PDF version of the presentation. Teachers are also able to email the PDF version of the PowerPoint to students or upload it to Google Classroom.
