Blog Recap: Functions and Algebra, Day 5 (July 31, 2015)



It’s hard to believe it’s the last day!

Today we….

We started with the post-test, to be compared by your code to the pre-test you took.  If you wish to know about your performance, you can email Andrew.

After the post-test Fran and Andrea led a discussion about the math problems participants posted the previous day.   This brought up topics such as the importance of vertical integration across grade levels, and how to achieve this goal (maybe re-create the activity with teachers at your school).

Andrea then orchestrated more discussion about “Math Talk.” She handed out a sheet with 7 talk moves on it (e.g., turn and talk, revoicing, repeating). We then watched three video clips, looking for the teachers’ uses of the talk moves.

Our abbreviated working lunch was spent filling out the course evaluations.  Afterward we did the Bungie Barbie activity: collecting data, using a best-fit line to make predictions, and then testing those predictions [in a theatrical manner].  Wrapping all this in a layer of friendly competition (congratulations, Nicole, Susan, and Trevor) made this an enjoyable application for our discussion of linear relationships.

We ended the day with a circle talk about professionalism, and making the most of professional development.  We then went around the circle to say what we gained from the workshops, both pedagogically and mathematically.  We also each set concrete goals for ourselves for the coming school year for something we would like to change in our classrooms.

Participate in the discussion group on Piazza, and read the articles in the Google Drive folder.  Read the solutions and commentary on the math problems, too.

Work to become the teacher you want to be.  Look the mathematics full in the face and don’t shy away from it.
