Wordsworth Poetry Help Please!

Hey everyone,
I'm in my final year at university and need some help with an essay. It's on the poetry of William Wordsworth, and i'm afraid i'm kind of lost. I've never studied Wordsworth before (strange i know), and i don't know where to start.
The question we have to asnwer is:

"Discuss the inclusion of the simple, the commonplace, and the dramatic in the works of Wordsworth."

And this is the list of poems we have been provided:
-We are seven
-Lined composed a few miles above Tintern Abbey
-Strange fits of passion have i known
-she dewlt among the untrodden ways
-three years she grew in sun and shower
-a slumer did my spirit seal
-i travelled among unknown men
-Michael
-I wandered lonely as a cloud
-ode: intimations of immortatity from recollections of early childhood.

Which of these poems most demonstrate the simple, commonplace and the dramatic? I only have 3000-3500 words to write on this so it can't really be all of them, so please, if anyone can help, just just two or three which best show these attributes.

Also, because i feel i need extra help with this, in what ways do the selected poems show these attributes? I hope to go into greater detail about them if possible.
