've been cruising around on the Google for Education blog this morning And rediscovered the "A Google A Day" website. The premise is simple. You have a question to answer using Google. The challenge is to refine your search enough to actually get the result. I know that many students often struggle with searching effectively and this seems to be a fun and engaging way to encourage them to get better. I can see using this as an activity to start off the week/day, a way to wrap up the week, or an activity to do for those kids who always seem to get done with their tasks much faster than everyone else.
I had a teacher ask me if there was a way to hide or remove students who are no longer in your class. The answer is maybe. It depends on if they are officially dropped from your class and appearing as red in your roster and gradebook. If not, then no, you cannot remove them until they have been unenrolled from the class. If the student is showing up as red in your gradebook though, you can hide them so you don't have to worry about them. Here is a screenshot to help you do it:
