Homework assignments for Alfred, Lord Tennyson's poem "The Kraken" will vary based upon what one desires to focus upon. Assignments can focus upon imagery, poetic devices, and/or mood/tone (to name a few).
For a more creative assignment, one could ask students to construct a picture of what the Kraken may look like. Tennyson provides readers with very specific images ("Unnumbered and enormous polypi / Winnow with giant arms the slumbering green").
One could ask students to analyze and define the poetic devices within the poem. Tennyson uses alliteration ("shadowy sides"), assonance ("thunders" "upper"), and repetition ("few, few") in the poem. Providing the names of specific poetic devices, one could have students identify and define the use of each within the poem.
Lastly, one could ask how specific words are used to define the tone or mood of the poem. Tennyson uses very specific words to define the mood he desires.
