Recently, the American Association of School Librarians (AASL) came out with their 25 Best Apps for Teaching & Learning for 2014. The apps were chosen because they foster innovation, creativity, active participation, and collaboration.
One app on the list is Shadow Puppet. This app fosters the student work creation and sharing, especially with presentations – users can upload images and record their voices, no account necessary. Besides presentations, Shadow Puppet can be easily used for storytelling.
The iOS-only app is free and is recommended for all grades K-12. Here you can see the finished product of using Shadow Puppet to make a birthday card presentation:
