Use the Import PDF premium feature to open your slides in Squid. Use Presentation Mode to cast your note to a TV or projector. Show your slides and write on them to highlight things or add to them. Some people even create only partially completed slides so they can fill them in during the presentation. At the end of the lecture, export your note to PDF and share it with your students through Google Drive, Google Classroom, via email, or using any app installed on your device that accepts PDFs.
