I was given great advice during my first years as an elementary teacher. In elementary school, we are asked to know cross-curricular content and build classroom communities. My mentor teacher said, "pick one thing to focus on this year, don't try to be great at everything." I choose my thing, it was building a classroom community where students felt heard and respected each other as learners. The model of holding class discussions would have fit into that goal. Choosing one thing doesn't give you permission to stink at the rest, just give yourself grace and know it won't be perfect. There is next year, to build upon your craft.

Let's assume that Josh is (or has become) decent at leading group discussions. Can we as math teachers provide Josh with the right discussion materials? For example, suppose Josh has chosen the Balloon Dog (thank you Dan and all other 3-act players). What comes after the "how long do you think Twinkie will take to finish all 100 balloons?" What math knowledge does Josh need to lead this discussion? Can this balloon dog play actually be a full week lesson at a level appropriate for both Josh and his students?

To this point, I offer a couple of prompts:

How far does Twinkie run during his popping?

How good is Twinkie at popping balloons?

How good is Twinkie at choosing the next target balloon?

If Twinkie chose the next balloon at random each time, what would be his result?

What if it were 5 by 5 instead of 10 x 10?

My overall point is that when Dan Meyer asks the room of teachers what do you see and what do you wonder, he gets a certain result. When Josh asks the same question, he should have some idea of where the conversation might go and materials to support the next steps.

The Desmos Graphing Calculator is a wonderful tool for discovery and for creating materials to support a lesson. Try this link for making balloon arrays of different sizes.
