Duplicate the presentation

Make an exact duplicate of the presentation Algebra Warmup — Week 5, name the copy Algebra Warmup — Week 5 (Copy), and move it into the Shared Teacher Resources folder so I can make edits without touching the original before Friday’s observation.

Before I duplicate Algebra Warmup — Week 5 for editing, highlight what will need attention in the copy: linked images, external video embeds, and notes that mention private student data. Make the duplicate ready for editing by removing active sharing links and adding a version note at the top specifying who will edit it.

I made a copy of Algebra Warmup — Week 5 to edit for Friday, but the embedded videos still point to the original file and won’t play for my co-teacher. I’m worried edits will break both files. What likely went wrong and what’s the fastest safe step to fix the copy so we can both use it independently?

I frequently intend to work in a duplicate but end up editing the original or producing copies that still reference the original’s assets. Where is the process failing, and what single change in how I create and name copies will stop accidental edits and broken links across shared decks?
