Google Slides: Import Master Slides
After several years of training teachers to edit the master in Google Slides in order to create digital learning spaces, I think I've finally figured out the best way to transfer the masters from one slide deck to another. In the past, I would have teachers use the import Slides option under "file" in the toolbar. A problem would arise where it would either import over existing slides or would not allow the user to choose from the layouts in the original slide deck. The method in this video seems to work better if you have activities stored away in a Slides presentation and want to transfer them to another lesson built in Google Slides.
