This looks like a really powerful storyboarding tool. I'd recommend trying it.

Paper is a lovely program for the iPad that lets you draw with just your finger. The free version has a limited set of colors and only one pen, but it's very soothing to use. You could use it just to capture comments from your students the way you might use index cards.

Storyboard That is a cutting edge Web 2.0 tool for rapidly creating amazing storyboards, no art skills needed. Great for business meetings and in the classroom for students to express their creativity. LL Note: If you want to print out the free version storyboard, it puts a big digital watermark across your pictures. I found a work-around for that: take a screen shot, then edit that picture as you need to. Short term, for small projects, it's workable. If I were going to use this on a regular basis, I'd ask my school to get us a subscription. It calls itself a storyboard program, but it really works much more like a comic strip. But it could be very useful for brainstorming in class. You can make 3 free storyboards a week, which might be enough for many of us. It's really easy to use, and you can customize some of the features with your choice of color.

This is useful if you need to fill in a document (letter, newsletter, flyer) with text just to see how it will look. I used this a lot when I worked in desktop publishing. Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book.

Flash card maker. Looks simple and straightforward.

This is what used to be Wallwisher.
