A friend at lunch one day said,” I know an app that you will love.” Well, he was right! Shadow Puppet allows you to narrate photos and saves it all as a video. I have used it with a study group, taking pictures of the whiteboard with our notes, recording info, then emailing the video of this to each student making studying at home much easier and much more independent. I used it today to take a picture of an old heater vent in my classroom and record the rattles so that I could send the resulting video to our VP to get the needed repairs. I have snapped photos of a student’s review sheet, recorded myself reading it, then sent it to students to help them study for a test.
This is a video I made for a student explaining Pyramid Facts (she joined our class after I had already taught it to everyone else, this got her caught up.)
The emailed videos can also be viewed on a PC.

Yes, the app is cool, but the pyramid, now that is super cool. Where were you when I was in grade school? Oh yeah, in diapers, lol. ~Nancy
