Thanks to edublogger for providing this growing list of class blogs.
I looked for some classes which were about the same age and quickly came up with a NZ school with a really interesting site. I commented on a couple of their posts and hopefully they will look at our blog.
This is the simple way I am starting to link up learning. I tried twitter earlier this year, but found that it was too unwieldy. Selecting the right people to follow was tricky and I didn't feel I could monitor the tweets unless I spent an unmanageable amount of time online.
I still need to get a manageable way to encourage children to post more on the blog...
