The proof above isn’t great. In the comments, take on any of the following questions (or any others):
- Sometimes kids slap stuff together when they’re confused, and other times they’re substantively mistaken. Which is this, and what evidence supports your position?
- How would you help this student recognize that the logic in his proof doesn’t flow?
- What would your next steps be in working with this student? What sorts of problems would you ask him/her to solve?
- From the picture above, what evidence of knowledge do we have?
