In Year 5 at the mo poetry is the order of business.
Three great sites I have stumbled across are below.
http://www.fizzyfunnyfuzzy.com
Loads of Kids poems that they can rate also a selection you can listen to.
http://www.poemhunter.com
A sight where you can search for poem by loads of authors.
Finally http://www.poetryarchive.org
A great site which has load of poems on. Many are also read by the author. There is a children's section as well. Best of all you can search the site by topic. e.g. all the summer poems.
That all for now.
