My students are already using Seesaw, so having them start doing a few BookSnaps would be relatively easy. Sometimes when we're researching a topic, I know my students can get a little bored with usual note taking. Students could highlight and mark up what they were reading for research purposes. They love adding emojis to everything, and might be more likely to think about how what they're reading makes them feel. I also like that they would be able to record themselves. My students do need to practice writing, but sometimes they just need to be able to get their ideas out as fast as they have them.
I also thought it might be nice to do some kind of William Allen White book club next year. I could have students post BookSnaps as they read. It would give us a starting place for discussion, and maybe even make it so we could have discussions among students who aren't in the same TAG groups.
