Glogster is an interactive poster maker which allows you as a teacher to create groups (classes) and give students access to these classes where they can create interactive posters. Posters can include video, pictures, animations and text just to name a few of the features. I have used Glogster with my students to create posters showing units of measurement. You have the ability to mark the posters within Glogster and add comments to each of the posters. To join Glogster click here and follow the instructions.
