  • Record your voice directly onto the slides and send the file to your students to watch at home as a PowerPoint slideshow. Insert > Audio > Record Audio.
  • Use screencast software (Screencastify, Screen Cast-O-Matic, Zoom, Loom, Google Meets) to record yourself sharing your screen. Upload to YouTube and send the links to students.
  • Hold a live video session (via Zoom, Google Meets, etc.) with your students and screen share the PowerPoint slide show.

You will need Microsoft PowerPoint to open. I also included a sample PDF with each resource so that if there are formatting discrepancies, you can match fonts (for free) to make it format correctly. Due to the nature of the clip artists’ Terms of Use, the clip art is locked, but the content is entirely editable.

*Bonus File!* Also included in this download is a bonus Unit-at-a-Glance! You receive a unit overview, part of the full curriculum map.

Need guided notes that compliment the PowerPoint? Here you go! These Interactive Notebook Notes use the same format and examples so your students can write the notes as you teach.
