In Rough Draft Math: Revising to Learn, Mandy Jansen discusses the powerful role of revision in math class. At first glance, we might wonder, what does it mean to "revise mathematics"? Make it more correct? Mandy argues that, yes, we can certainly revise to make mathematical work more accurate, but students' explanations, definitions, proofs, justifications, or representations could also be improved by becoming more precise, detailed, elegant, concise, convincing, illuminating, and more.
In this table, Mandy describes several goals students and teachers might consider when revising. Through classroom stories and analysis, Mandy shows how looking at student work with these goals in mind can transform both discussions and culture in the math classroom. What might happen if you select student work to share out because it would benefit from revision, whether it's correct or incorrect? In Rough Draft Math, Mandy tells powerful stories of students standing at the document camera with pen in hand, seeking and receiving feedback that helps the class clarify thinking and improve their mathematical work.
"Rough Draft Math: Revising to Learn has the potential to dramatically improve the quality of mathematics teaching and learning for all students by opening spaces in classrooms and creating new opportunities for students to show their mathematical brilliance as it unfolds and is in progress." - Imani Goffney, Assistant Professor, University of Maryland and Co-Editor, Rehumanizing Mathematics for Black, Indigenous, and Latinx students
