For our class blog, I use KidBlog. It's specifically designed for teachers to use with students. You can control comments and settings, which I feel is very important.
The assignment for this blogging session was created by our Tech Integration Teacher (so lucky to have one!). We discussed the importance of choosing truths that were very unique and outrageous to match an outrageous lie, or picking a lie that sounded believable enough to be true and fit in with more "normal" truths. The kids did a great job!
The kicker was that when they finished their own post, they then had to comment on at least five other blog posts. In their comments, students were told to single out the false statement and explain why they thought it wasn't true using thoughtful reasoning.
Here are some of my favorite posts:
I joined in on the fun, too! Here is a screen shot of my post:
Not to brag, but I got the most comments! :) Once the kids get five or more comments on their posts, they are allowed to reveal the "falsehood" (yay vocabulary!). Can you guess which one was mine?
