You want a quick way to capture key ideas that students need to know about a particular text. Rather than just have them make a concept map, outline, or highlight a copy of the text, why not get them to make an animated GIF summarizing key concepts?
If vocabulary, include the definition, as well, and a picture of what the word. Or use a series of pictures to share the intent of the key idea.
Task
Create an animated GIF summarizing in simple words and rich images a story of your choosing.
Some ideas:
Create a series of slides in Google Slides or Powerpoint illustrating a story, then put them into Gifmaker.me
Microsoft Paint or Paint 3D
Step 2 - Create the Animated GIF
Create the key idea panels for each aspect of the non-fiction text you wish to summarize or illustrate
Save the pictures, or take screenshots of the pictures, then save them
Put them into GIFMaker.me website to create your animated GIF
