I love using Google Slides. I use it all the time to create handouts for my students because I can insert images and text boxes easily. Another time I really appreciate Google Slide's versatility is when I am creating a Google Site and want to create math problems for my students to complete. I can save an individual slide as a JPEG or PNG image that can easily be embedded into the site.
Here are the steps I take when creating an image from a Google Slides presentation.
1. Create your problem on the Google Slide.
2. Click on the File tab
3. Click download as JPEG or PNG image. You can then save this image to your computer to use however you would like!
