Check out the NEW TEMPLATES in Google Slides! They're awesome!
When I first saw Templates on the right side in Google Slides, I thought that it was replacing Themes because Themes is usually showing on the right side when Google Slides opens. Thankfully, this is not the case. We still have Themes and now we have Templates, too! If you want to see Themes instead of Templates, just click on the word Theme at the top of Google Slides and Themes will open in the right side navigation pane instead of Templates. Also, if you want to see Templates but they're not showing, just click on the Slide tab at the top of Google Slides and then click on Templates. We have so many new templates to choose from that it might be hard to make up your mind. As you scroll through the new templates, you can click on any of the templates to see all of the slides in the template. You can click on any slide in a template to add it to your presentation or you can insert all the slides from a template into your presentation.
