Skitch, a free app
I have visited most second-grade classrooms for students to make predictions of where they think the iBoat will land. Skitch has a built in world map feature where you can zoom or pan then annotate. Students worked collaboratively to annotate a map using: text boxes, arrows and the pen tool. Below is a sample.
Another useful feature of Skitch is that you can annotate photographs from anything on your camera roll. Here are a couple of ideas:
This one is a screenshot of a website. It is great practice with creating nonfiction text conventions.
For doing a think aloud about a text, display it on the large screen with the LCD projector along with some annotations to mark your thinking. Also, exclamation points and check marks are other stamps that can be used. Good to know that there are only so many characters you can include next to the stamps.
As a way to digitize anything where you can mark it up and refer back to the saved image.
If you are interested in trying out Skitch, download the app to your iPad and play with the features.
Tools:
crop stamps add text arrow pixelate line & shape tools
pen & highlight tool.
Also check out the share feature. Here you can include a caption.
Here's a link to a great guide put out by Skitch. Here's a link to a blog post by Nicole Gleason, Tech Integrator in SAD 6 on ideas for using Skitch with young students. Please let me know if you find any good uses for Skitch or if I can help you!
