In The Language Police, Diane Ravitch includes Poe in her list  for Grade Nine. She writes: 

Poems suggested for high school readers include "To Helen," "The Bells," "Israfel," "The Raven," and "Annabelle Lee." Among the short stories: "The Telltale Heart," "The Pit and the Pendulum," "The Murders in the Rue Morgue," and "The Fall of the House of Usher." (p. 225)

     The complete text  is available on the web at the E. A. Poe Society of Baltimore: http://www.eapoe.org/works/index.htm. I have used the version from The Works of the Late Edgar Allan Poe, 1850, vol I, pp. 346-352. 

     Based on the first and second stanzas of the poem, these two exercises are approximately equal in difficulty. Although there are a fair number of verbals and appositives in this poem, my guess is that, unlike in many poems, the vocabulary here will give students more problems than will the sentence structure.

     I immediately settled on the opening paragraph of this story as the selection for the exercise because it contains so many subjects and complements that both follow the finite verb. It should, therefore, be an interesting exercise for grades five or six. It can, of course, be used in any grade in which the students read the story. The selection for this exercise was taken from the complete text of "The Tell-Tale Heart" that is available on the web at the E. A. Poe Society of Baltimore: http://www.eapoe.org/works/index.htm.
