Natalie started by emailing photos of 3 tools to each student. Students saved the photos to their camera roll. They chose one picture, opened it in the app and began entering info about the tool on the trading card that they selected. I think the thing that I like most about the app is that it asks guiding questions to help the students decide what they want to include on their cards.
The final products could be emailed and/or saved to the camera roll.
