Integrating Web 2.0

We are starting the school year doing the Geography of the United States. One reason for this was to do some cross-themed programming with our English units for the Salute to Seuss project, but another reason was to give the students plenty of opportunity to explore what blogs were and how they were used.
We have a clustrmap on our classroom blog page, and we also have a huge US map hanging on our bulletin board. We're using Avery's 1/4" clear, removable dots to track people who visit our blog. We're not changing sizes or colors the way Clustrmaps does. At some point, we might add a world map to the bulletin board, but for now, I think the US Map is a good way to start.
This unit is also giving me the opportunity to help my students understand time differences, and learn a little about other places in the United States. We're starting with the West Coast, because of my trip to Redmond in about a week. As I mentioned in the last blog, I've left work for my students to do that relates to my trip. I've also promised to post pictures and details. I will actually post pictures and details here as well, although the classroom blog will have top priority for me.
In any case, if you're interested in looking at one of the activities the students will do while I'm gone, you can go over to my wiki and find this activity: Track A Flight.
