I found this great app called Snapguide. Snapguide is a way to share and view step-by-step how to guides. You can also create your own guides and share what you love making with your friends on Twitter, Facebook and more.
I made a quick how-to guide for my first grade students to try it out. You can add photos, text and video. I love that you can share it, embed it in a blog, or even print it out.
I think this would app would have a lot of great applications in any classroom. I think it would be fun to have students create their own Snapguides as well. My 8 year old son made one on how to make an origami Yoda and he had a lot of fun. I look forward to using this with my students.
