This one is really interesting. We’ve got both a sample of student work, and on the left the student has crossed out \frac{5}{1}. We also have a record of the following student question:

Kid: [Raises hand.]

Teacher: “What’s up?”

Kid: “Are you looking for a 1 or, like, the number 1?”

What is the student’s question, and what does it reflect about what he knows and thinks? How would you help?

[The submission also comes with an answer, yielded by the teacher through further questioning, revealed in the comments.]
