Practices for Orchestrating Productive
Mathematics Discussions
INVESTIGATING THE FIVE
PRACTICES IN ACTION
Tiling a Patio
In the Case of Darcy Dunn there were three
equations that the students produced during
the discussion.
 w=2b + 6
 w=2(b+2) + 2
 w=3(b+2) – b
Did anyone produce a different equation that
can be shown using the patio?
The Case of Darcy Dunn
 Take five minutes to review the reading from last
night and the five practices on page 8.
 In your small group identify places in the lesson
where Ms. Dunn appears to be engaging the five
practices.

The Case of Darcy Dunn
 I have posted the 5 practices on chart
paper.
 Next to each practice let’s list the line
number where we see the practice
used.
 Justify you response.
Analyzing
The Case of Darcy Dunn
 Do you think Darcy Dunn’s lesson was
effective? What leads you to that conclusion?
What did she do beyond the five practices that
may have contributed to (or detracted from)
the quality of the lesson?
 What if anything, would you have liked to see
Darcy Dunn do differently? How do you think
the changes that you propose would have
affected student learning?
Analyzing
The Case of Darcy Dunn
 Read the pages 26 – 28 .
 To what extent do you agree or
disagree with the authors’
perspective?
