Do you have trouble getting your kiddos going at the beginning of class? Especially first thing in the day (like right now)? I came across a link to a webpage entitled "365 things to make you go hmmm..." that features a thought provoking question each day to get your brain going. There was a question posted a couple days ago that asked "What color is snow?" That would make for a great one today. At any rate, by utilizing this website at the beginning of class while your students are starting to come in, you can get them focused on thinking. Better yet, it's already done up for you so you don't have to come up with a question on your own. Click on today's question, below, to go to the site.
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:
