Suzanne at the Math Forum

In the work that I’m doing at the Math Forum I’m often in middle school or upper elementary classrooms and I have the Mathematical Practices on my mind. Also recently I’ve been at New York’s state mathematics conference (AMTNYS) and Pennsylvania’s (PCTM) and one of California’s (CMC-North) and the presentations and conversations have centered around the Common Core and, in particular, the Standards for Mathematical Practice. It’s occurred to me that one small detail is easily lost –> the goal is for the students to develop these practices.

What does it mean to have students “Make sense of problems and persevere in solving them.”?

Both parts of that practice require quite a shift from the practices that have become popular in classrooms feeling pressure from NCLB and the standardized tests that have been used to measure students’ success.

In classrooms where the teacher shows how to do the problem and then the students practice what was shown to them, it is the teacher who is making sense of the problem and not the students.

In classrooms where the focus is on the student making sense of problems, we should hear phrases like:

How do you know?
Can you tell me more?
What did you do?
Does that make sense?
Why do that?
Why did she say that?

If we only have to focus on one person’s practice (our own as the teacher) we have a much easier to control job than if we have to focus on each students’ practice! This change requires a major shift in our classroom environment.

Similarly, the second half of the practice “… and persevere in solving them.” also needs to shift from the teacher demanding that students persevere (or suffer the consequences) to where the students have a “practice” of persevering because they are involved in problem solving as a process.

Students who
- engage in a problem over time,
- talk about their ideas,
- use a variety of representations,
- write their ideas and receive feedback,
- reflect on their ideas and revise
… and more …
are persevering!

Establishing the expectation, believing in the students and helping them learn the routines to complete the process of problem solving is the role of the teacher. Those teachers will be helping their students develop  ”The Standards for Mathematical Practice.”

Both on October 22 at Germantown Academy in Fort Washington, PA and most recently on October 27 in Rochester, NY, I presented sessions about problem solving and the CCSS Mathematical Practices. In both venues we agreed that one of the more difficult challenges is to slow things down so that students have opportunities to:

1. Make sense of problems and persevere in solving them.
3. Construct viable arguments and critique the reasoning of others.

Neither of those practices can be done well in a rushed atmosphere where the goal is to check off the “skills” that a student has mastered. Recent years have had this “quicker is better” tone. Teachers have been encouraged to cover everything that might possibly be on the standardized test. They have had long checklists of what the students must learn. Now, with the Common Core there is a return to a focus on process but how do we help make that happen? A change in classroom culture takes time and effort. Approaching problem solving as a process over time is one idea that might help.

I provided some ideas to focus on the process of problem solving and the communication that accompanies it:

* start a problem by reading it as a “story” and then ask students “What did you hear?”
* don’t plan to finish a problem in one class period — work on parts over time
* use our Noticing/Wondering activity with students working in pairs or groups
* use technology to approach a problem with virtual manipulatives when you’ve first introduced it with concrete manipulatives or vice versa
* start a problem at the end of the period, wait to re-engage until a day or two, and continue to do a little each day
* encourage students to read their solution drafts out loud to a partner and then discuss what the listener might still be wondering
* take time to give feedback to each student — it could be as short as “I notice … (one thing).” and “I wonder … (one thing).” If the teacher values the process and provides feedback, it models to the student that their initial draft is worth reflection and revision.

ATMOPAV Mathematics & Technology Conference, Fall 2011
Suzanne Alejandre, The Math Forum @ Drexel University, Philadelphia, PA

Saturday, October 22, 2011
Session 3: 1:15 to 2:15 pm
Middle School (grades 6-8)

The goal of the Math Forum’s problem-solving process is not to be over and done. It is to think, express, reflect, and revise. Leave with problems to try with students.

I. Introductions

II. The Math Forum’s Problem Solving Process — let’s experience a short version together!

III. Debrief that experience

• what did you notice?
• what are you wondering?
• CCSS Mathematical Practices
  1. Make sense of problems and persevere in solving them.
  2. Reason abstractly and quantitatively.
  3. Construct viable arguments and critique the reasoning of others.
