For students to engage in rough draft math, they need spaces to share their initial ideas while they are in progress. They also need opportunities to revisit and revise those ideas so their thinking can continue to evolve. These spaces and opportunities begin with tasks that invite students to communicate their thinking about ideas. Students are more likely to encounter a task like Task A in their math classes. This chapter discusses how task selection and implementation can foster opportunities for students to think about concepts and communicate their thinking. Certain tasks provide more spaces for students to deepen their mathematical understandings through rough draft thinking. Tasks with more than one good answer foster discussions about mathematics and opportunities to revise thinking.
