One piece includes reviews of websites and technology tools. I try not to get caught up in the tools, but I find it handy to have reviews of them to help me determine what would work best for a specific lesson or need. I can't try out every tool and really explore it the way I would like, so this is a pretty nice substitute. In that vein, I recently wrote a review of Primary Wall for this section of teachinghistory.org. It's basically an online wall on which folks can stick post-it notes. My first graders enjoy using it.
