My students are beginning the play, Romeo and Juliet. I often take snippets of language and provide the kids with access to the OED, annotated versions of the complete works of Shakespeare, and various other dictionaries and references, and challenge them to figure out what the quotes mean. However, packaging is important if you want to persuade teens. The playing cards seemed to add a more fun element, and persuade the students to look at the challenge as a game. It also helped me to differentiate the instruction invisibly by distributing cards of varying complexity to different students.
