My elementary school friends know all about Shel Silverstein's website. I've waxed poetic about it for years (sorry, pun only slightly intentional). I had my son read along to Shel himself reading to help with his fluency. I can't say enough about this site for kids!
For older tweens and teens, the Library of Congress has a Poetry Page that includes information about and by the Poet Laureate of the United States. Additionally, there is a link for "A Poem a Day" for high school students and a featured webcast of poetry readings (often by the poets). I was drawn to the Walt Whitman link to the American Memory collection.
So, I hope this report, though short-but-sweet,
Is better late than never.
And when on this blog next month we meet,
I'll be timely in the endeavor!
