DO NOT USE SPARK NOTES. STUDENTS HAVE READ AND ENJOYED THIS BOOK FOR YEARS WITHOUT SPARK NOTES.
Use the annotation example and acronyms to help you. For chapters two and three of Lord of the Flies, you should annotate the text. To do this, you should make note of anything in the text that you think fits under the heading of "author's purpose." You can consider how the author uses imagery or how the author develops characters, you can look for examples of foreshadowing, you can look for ideas embedded in the text (in other words, THIS is what the book SAYS--what might it say about what the author THINKS?), and you can continue developing ideas about themes you identified in chapter one. You can also write about anything else you see going on in the text--from a line you like for a particular reason to a detail that you find interesting or significant. If you need other ideas what analysis can look like, look at the document entitled "annotation example" in the "resources" section. If you need other ideas on the kinds of things you can look for, scroll through the "annotation acronyms," also located in the "resources" section. You may find D.I.D.L.S, T.A.P.S, and D.I.T.S. helpful because they deal specifically with the elements of literary analysis.
Write on your own paper. Shoot for at least one example per page, but don't necessarily limit yourself to that. Identify where your example is on the page, either by line number or paragraph.
