Let's face it, the last chunk of 1984 is the O'Brien show. The things he says can be VERY confusing to students.
This is a selection of the "Top 10 Quotes." This sheet asks students to explain the 1984 idea AND the idea why Orwell would make this character say these words.
You can easily alter this assignment as well by jigsawing out the quotes and then having the students share out.
