Here is a PowerPoint file I made using the OfficeMix add-in. The aim was to show my Grade 8 students some basic skills in MS Word that they will need. I created a video for each skill demonstrating how to perform a task in MS Word. At the end there are some files that they can download and edit to practice the skills.
See below, for members of the site, the OfficeMix presentation and files you can download for your students.
