In February, I gave a webinar for TERC's Forum for Equity in Elementary Mathematics. I was honored to be invited to speak -- it's an impressive lineup! -- and Karen Economopoulos and I conceived of my talk as a direct follow-up to Marilyn Burns' December session, "Reasoning: The Essential Foundation for Building Students’ Understanding." Marilyn explored numeracy through the lens of clinical interviews with elementary students; my talk would take up the question of what to do once we've learned about student thinking.
My undergraduate advisor Robert Davis told us (& I'm paraphrasing): When the moon is full, you can see the man in the moon. Look again. Can you also see the rabbit in the moon? Then it's possible to see many more things in the moon. Keep that in mind sheet you're teaching your students.
Now I'm wondering about if it's a good problem for kids and, if so, what grade.
