Pages is a powerful but easy-to-use word processor and page layout application that works on both Macs and on iOS devices. While many students may elect to use Google Docs to collaborate on documents, Pages excels in making work look good, in combining text with movies and graphics, and in creating files that can be exported as PDF or as Microsoft Word files. Pages is a companion app to Numbers (spreadsheets) and Keynote (presentation slides) and comes free with every iPad.
Documents created in Pages can be "sent" to other applications on iPad. If students are working on an original document within Pages, they can, for instance, send their document to Schoology to hand-in an assignment.
