How can I discuss Tom's and Huck's physical, personality, ethical, and emotional traits in eight paragraphs?
If you are required to write an 8-paragraph essay on these two characters, I would suggest the following format:
1st paragraph - introduction with thesis statement
2nd paragraph - Tom's physical traits
3rd paragraph - Tom's personality/ethics
4th paragraph - Huck's physical traits
5th paragraph - Huck's personality/ethics
6th paragraph - Compare & contrast Tom and Huck physically
7th paragraph - Compare & contrast Tom and Huck ethically/personalities
8th paragraph - conclusion
Of course this is not a "set in stone" way of writing an essay, but it would give you a good framework to begin with. Also remember that it is very important to use properly quoted examples from the book to support what you are saying about these characters.
