There's no LABOR when you use BUILDING BLOCKS in Google Slides because they're all ready to use!
You can access Building Blocks in Google Slides by clicking on Insert and Building Blocks. You can also click on the Building Blocks icon on the Sidebar in Google Slides. Both ways open the Building Blocks panel. There are 14 different categories of Building Blocks so you have lots of choices. Some categories are Agendas, Lists, Headlines, Text Callouts, Collages, Badges, and Calls to Action, to name a few. When you click on a category name, you can scroll through and see all of the Building Blocks in that category. All you have to do is click on a Building Block to insert it into your Google Slides presentation. After a Building Block is inserted, you can edit the Building Block by resizing it, moving it, changing the colors, text, pictures, etc. You can even use multiple Building Blocks on one slide!
