I do this in the math classroom, Katie. When I taught geometric proofs and trigonometric identities, I would capitalize on student’s experiences with writing in their English classes. In addition to two-column, flow-chart, and paragraph proofs, our team collaborated with English teachers to design an outline structure that follows the thought process/organization of an argument (claim/evidence/warrant). Nothing like collaborating across content areas!
What I love most about your post is the introduction to the task through a discussion about ways we communicate. It has an extremely low floor and multiple entry points for any experienced learner to engage with, but also has the potential to turn into an existential discussion. Might have to steal it when I get back into the geometry classroom this year.
