Students will be able to use today's class to finish up work as needed.

We have covered a lot over the last few days, and now students have a chance to make sense of it all.

10 minutes

I post an opening problem asking students to convert both 3 radians and 3π radians to degrees. I circulate throughout the room and look to see what students understand. How this problem goes depends mostly on how far students have gotten on their practice; the second module of the current Delta Math assignment helps specifically with converting radian measures that are not given in terms of π.

This problem helps students **attend to precision** because it provides a very simply illumination of what a difference π makes when included in an expression. Students can be slow to get used to writing and saying out-loud the "pi" part of radian measures, but usually by talking through this problem that distinction becomes clear.

Wherever the conversation goes, there are two ideas I make sure to touch on: the necessary calculation for 3π radians is actually much easier that the one for 3 radians. Also, the degree measure for 3 radians (~171.9 degrees) is nearly, but not quite 180 degrees, and I encourage students to think about how this relates to 3 being *not quite* as much as π.

A note to teachers: ok, I recognize that all of these narratives are "notes to teachers," but this one is less about today's lesson and more about my curriculum in general. I am including this lesson as a way of sharing what really happens in my classroom. Today is just an open-ended work period, and I really try to stay out of the way as students decide what they're going to work on. There is plenty to do: revisions to the Defining Pi Project, last minute finishing up on the project, the current Delta Math assignment on radians and arc length, the Unit 2 review, the construction of a perfect "Cheat Sheet" for the upcoming Unit 2 exam.

Days like this are very important. To me, for my students, for our relationship, and for their self-efficacy.

We circle up to check in at the end of class. I ask everyone to share a just a few words about what they did today.
