This is a brief PowerPoint presentation that serves as an introduction to poetry. It contains a brief intro to the concept itself, some quotations, followed by definitions and some examples of seven types of poetry. (Haiku, concrete poetry, balled, limerick, epic, free verse, and epigram.) Some of the examples are YouTube links.
I used it for my grade 9 class, but I think it's suitable for grades 7-10. It's meant to get their feet wet and explore the various types of poems out there before we went into deeper analysis of selected poems.
