Students can check to make sure their animation is in sequence.
With the example below, we have created six images of our star. If you look closely, you can see the image of the star is moved slightly to the right in each successive picture. This was a simple animation using just the lasso tool in the tool bar and moving the image slightly to the right. Animations can be much more complicated. Students can have clouds move across the sky by adding some white on one side of the cloud and erasing some of the white on the other end.
