I used these background images with lower primary grades in the Innovation Lab during National Talk Like a Pirate Day. We had small groups come into the lab to record their pirate talk. Then I placed the background images behind the students using Green Screen by Do Ink app.
Videos are recorded in front of the green screen using the regular video app on the iPad. Then I used one my custom made background images from the download to procure a background image that replaces the green screen.
