This document discusses how students can use iPads and apps to demonstrate their knowledge and engage with content in new ways beyond traditional worksheets and assignments. It provides examples of several apps - Explain Everything, Creative Book Builder, Tellagami, and iMovie - that allow students to create video screencasts, digital books, animated stories, and movies. The document suggests how these apps can be used across subjects for students to explain math problems, write and publish digital books, create character narratives, and produce video projects. It emphasizes that these tools allow for more authentic writing in different formats, facilitate discussion and sharing of work, and provide an electronic portfolio system through uploading projects to the Canvas platform.
