I use this anticipation guide to get students thinking about many of the different messages and/or social/societal challenges that Ins Choi's play 'Kim's Convenience' discusses.
After writing their opinions, I get my students to talk with a peer and discuss what they think. I reinforce the idea that it is perfectly fine for them to disagree on ideas, but they have to be respectful in doing so. After this 5-10 minute discussion, I get my students to write an explanation about what they talked about - what did they agree most strongly on? Why? What did they disagree most strongly on? Why?
After reading the play, students can re-read what they wrote for each statement (and their original summary of their discussion with a peer) and write a paragraph explaining how the play reinforced and/or challenged their original thoughts/opinions.
I use this in my 10-1 ELA class.
