I made a screencast (easy) of how I created the google map with everyone's summer travels. You will need to align this after you start by scrolling up/down and left/right. Also, if you scroll down there is another screencast of a mathematics review. After I completed the screencast, it asked how you would like to produce it. As you can see from the size difference, I chose two different formats. This was not intentional, but I've learned it needs to be somewhere in between my two choices.

Here's an example of a screencast that you could make (or your students) to place on your web page, blog, or wiki.
