This is a one-page lesson plan which includes an aim, do-now, instructional objective and lesson in which students learn what an allusion is (definition included) and how to analyze allusions in Mary Shelley's Frankenstein.
There is a graphic organizer for visual learners. I'd recommend making copies of this lesson plan to hand out to the students or simply have them copy it down if you are going to present this on an overhead or projector.
There are three columns on the chart / graphic organizer, and I found the third column particularly useful but it is the column which asks the students what it was they discovered as a result of the allusion. Having the students think about what they now understand makes a huge difference.
I hope your students enjoy this lesson. I used this lesson and improved upon it for about three years. If you like this lesson on Frankenstein, please look for my other Frankenstein based lessons.
