The purpose of this tool is to highlight the diversity of
student thinking, misconceptions, alternate solutions,
and connections so any student, regardless of level, can
contribute in meaningful discussion and gain agency
and deep conceptual understanding.
Teachers also build pedagogical content knowledge,
cultivate the exibility to work with diverse students,
and practice continuous improvement.
This tool is designed for middle school math teachers, but
can be adapted for any grade level. It is used for planning
the lesson, data collection during the lesson, as well as
reection after the lesson and for future planning. It is a
cyclical, living practice of continuous improvement.
To use this tool, follow the Planning
Checklist, which breaks down the
process into four distinct parts: Un-
derstand the Activity, Plan the Ac-
tivity, Collect Student Samples and
Thinking During the Lesson, and
Reect on Content Understanding
After the Lesson.
First, Understand the Activity by
reading 5 Practices for Orches-
trating Productive Mathematics
Discussions, how to choose cogni-
tively demanding tasks, and how to
facilitate equitable student discus-
sions and honor student responses.
Next, Plan the Activity by identify-
ing a specic learning goal, task,
content, and math practice. Antic-
ipate student strategies that may
be used, practice sequencing stu-
dent thinking, and consider virtual
adaptations and necessary adjust-
ments.
Then, During the Lesson, collect
student samples and data, and
guide student discussion.
And nally, After the Lesson, exam-
ine what student data says about
your students’ current level of un-
derstanding, identify student re-
sponses you did not anticipate or
understand, and identify potential
areas of development for your own
content understanding.

Equitable Math Discussions
through Student Discourse
Introduction
Have you ever taught a lesson and then encountered students solving the presented problems in a different way?
Do opposing student thoughts scare you or excite you?
Is your rst reaction to differing thoughts “Tell me more!” or “Let me show you”?
Purpose
The purpose of this tool is to highlight the diversity of students’ thinking, misconceptions, alternative solutions, and
connections so any student, regardless of level, can contribute and gain equitable access to grade-level content. Stu-
dents gain agency, voice, and deep content knowledge through carefully planned discussions. Teachers also build deep
content knowledge, cultivate the exibility to work with diverse students, and practice continuous improvement.
This tool is meant to be used with all grade levels and content. It is used for planning the lesson, data collection during
the lesson, as well as reection after the lesson and for future planning. It is a cyclical, living practice of continuous
improvement. For a detailed demonstration on how to use this tool, see the short video here.

, is
the foundational reference for this tool. It involves ve stages for highlighting and sequencing student thinking:
1. Anticipate likely student emerging ideas and alternative solutions to mathematical tasks.
2. Monitor students’ actual responses to the tasks.
3. Select student responses to feature during the discussion.
4. Sequence student responses in a purposeful order to build a coherent math story.
5. Connect different students' responses through math discussion.
Understanding this practice is the major step to begin implementation. If you are not familiar with the 5 Practices, it is
recommended that professional development, coaching, and independent research be coupled with this resource. Level
1 and 2 readings are must reads, and level 3 is an optional deep dive.

I can decide whether or not two situations are happening at the same rate.
Diego paid $47 for 3 tickets to a concert. Andre paid $141 for 9 tickets to a concert.
Did they pay at the same rate? Explain your reasoning.
Students will work individually. Their solutions will be shared anonymously.
Students will compare their strategies at the end of the lesson.

context of a ratio relationship. Expectations for unit rates in this grade are limited to non-complex fractions.

Since 9 is 3 x 3, multiply 47 by 3, 47 x 3 = 141 . Diego would
have paid $141 for 9 tickets if he paid at the same rate he did for 3
tickets. Since this is what Andre paid for 9 tickets, they paid at the
same rate.

The students are in different places along the continuum. There were
4 students who leaned on additive reasoning rather than multiplica-
tive reasoning. I was able to connect their reasoning to the double
number line and model the multiplicative reasoning.
Once we discussed the double number line, I connected it to the
method of multiplying by a factor of 3 and compared it to the divi-
sion model.
We concluded with the unit rate strategy.
This student data tells me that students are in various places. I inten-
tionally started with the misconception, (i.e. using additive reason-
ing) and moved from representational to abstract, so that students
can make connections between their method and the more abstract
methods.
The goal for this unit is to build conceptual understanding, so I will
continue to make connections between the various approaches.
I need to push myself to continue to approach ratios in a conceptual
way, rather than rushing to teach a procedure. I want to continue to
understand the connections between the various strategies used to
solve these types of problems. I need to study how ratios will show
up in 7th grade, and make sure that I am setting students up for the
7th-grade approach.
Discussion for Professional Learning Community (PLC):
How can I “honor” a wrong strategy?
Is there an equity-oriented way to approach wrong strategies?
When does the additive strategy apply or make sense?
Can I think of a time or example when that strategy
does work or apply or make sense?
Why do we as math teachers see this an absolute correct approach?
Misconception:
Using additive reasoning
3 + 6 = 9 and 47 + 94 = 141
(got stuck)
(4 students: Students G, I, R, S)
47 goes into 141, 3 times and 3 goes into 9, 3 times,
therefore they paid the same price.
(3 students: Students T, U, V)
The next lesson introduces
ratio tables. I need to be sure
that I show the relationship
between each of the methods
shown today and ratio tables.
I also can help the students
who relied on additive
reasoning to see how they
can translate to multiplicative
reasoning using a ratio table.
I will make the connection
for students who relied on
additive reasoning to see
how they can translate to
multiplicative reasoning using
a ratio table.
I will show the students who
divided that they are using
multiplicative reasoning.
