I used to love the spinning vortex activity from the Lesson Activity Toolkit. When the toolkit was updated, it was sad that it didn’t seem to spin any more. Now, I know that it was taken away for a good reason; children with epilepsy can have a spell triggered by the spinning. However, none of my students has that problem. I found out that when I edited the file, at the top right of the activity, there is an option that you can check to turn the spinning on. Hurray for SMART! Good idea.
