ABCYA! Animate is an easy to use tool for students to create animated GIFs. Students have up to 100 frames to come up with their creation. They have the ability to select a background or insert objects from a set of backgrounds and objects offered by ABCYA. There are the usual tools for students to create their own backgrounds and objects via a pencil, paintbrush, text and shapes tools. The ability to save the animations as an animated Gif allows students to embed their creations into a website, blog, google+, Smart Notebook, or PowerPoint.
Below is an example of a quick animated GIF that I created using ABCYA animate.
