I first heard about Scratch, when one of our attendees gave a brief show-and-tell on it at Boing Boing's Weekend of Wonder. It sounded pretty accessible. It came to mind again when recently, in an attempt to get my daughter to use the iPad for more than watching Bratayley, I decided to try and interest her in creating something. She loves art, but Minecraft was far too confusing for her and I was looking for another kid-friendly programming option. ScratchJr is a tablet based, even simpler version of Scratch, installing was as easy as any other app.
The Official ScratchJr Book does a great job, with friendly illustrations, of walking us through the basics. My daughter prefers the painting and drawing of characters, and backgrounds, to the organization of blocks, but the book did a great job of walking us through it all. Having gone through the book together, once, she can now refer to it one her own, if she runs into a problem. Generally, her problem is me grabbing the tablet and adding things.
I am not going to tell you we've made high art, but I think I could throw together a decent 1980's King's Quest parody.
