Investigating the Five Practices in Action

2. 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?

3. 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.
Anticipating
Monitoring
Selecting
Sequencing
Connecting
Use the line numbers to help you keep track of the places here you think she used each practice.

4. 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.

5. 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?
