Out to lunch…
“I’m not good
at math, you figure
it out.”
Last week, I was
at a restaurant
with a group of
friends. The bill
came and this is
what was said…
Next time we go…
“I’m not good
reading, can
you read this
to me?”
Same Reaction?
Illiteracy
Innumeracy
Why is it socially
acceptable to be
innumerate?
Innumeracy
21% of Americans possess
numeracy skills at the lowest
level . . . [which] means that
people cannot . . . work out
the change from $2 when
buying goods worth $1.58.
(Murray, 2000. p. 2)

not released in time, you can simply
say “What do I do first? I can’t take

the 1 and …”. Teachers always
get a chuckle out of this.
Procedures & Algorithms
At your table, fill your large paper with
examples of algorithms/procedures
you learned as a student.
Examples:
Foil method in algebra
Butterfly to compare fractions
Standard Algorithm for multiplication or division
Algorithms
Choose one procedure or algorithm
that you learned as a student.
E.g., Finding common denominator,
FOIL, Butterfly to compare fractions,
multiplication or division algorithm,
dividing fractions
Do a sample problem using it…
Then explain it to your neighbor –
explain the process and why it works
Algorithms
What algorithms did you explain?
How does understanding the math
relate to following the steps of the
algorithm?

According to the
Common Core,
What is MOST
IMPORTANT at
your grade level?
Answer by placing
one sticker on the
chart.
The Three Shifts in Mathematics
Authors of the Common
Core Math Standards
have emphasized 3
shifts from old state
standards
(like the NCSCOS)
Focus
Coherence
Rigor
Shift One: Focus
strongly where the Standards focus
Significantly narrow the scope of
content and deepen how time and
energy is spent in the math classroom
Focus deeply only on what is
emphasized in the standards, so that
students gain strong foundations
Why Focus?
The U.S. curriculum before the
Common Core was known as ‘a mile
wide and an inch deep.’
What did this look like in the NCSCOS?
Focus is necessary in order to achieve
the rigor set forth in the standards
Mathematics topics intended at each grade

Schmidt, Houang, & Cogan, “A Coherent Curriculum: The Case of
Content Emphasis
Focus
Designed to help
teachers focus on
what is most important
at each grade level.
Content Emphases by Cluster
Not all of the content in a given grade is emphasized equally
in the standards.
Some clusters require greater emphasis based on the depth
of the ideas, the time that they take to master, and/or their
importance to future mathematics or the demands of college
and career readiness.
An intense focus on the most critical material at each grade
allows depth in learning, which is carried out through the
Standards for Mathematical Practice.
Focus does not mean neglecting certain standards.
Neglecting material will leave gaps in student skill and
understanding and may leave students unprepared for the
challenges of a later grade.
Sample Content Emphases

Coherence Within Grade
Use the handout of your Grade Level
Clusters
Analyze how these clusters are classified
How do these clusters overlap or
address similar “larger concepts”?
How do Supporting Clusters align with
Major Clusters.
Coherence
Pick a unit from Investigations that
incorporates multiple clusters
What are the pre-requisite skills
you hope students have before this
unit starts?
As students are doing the work in
the unit, what is the Major Cluster?
What other clusters are also
incorporated?
Coherence
Move and group with teachers from
multiple grade levels
Exchange ideas and discuss what
your grade level came up with
Coherence Wrap-up
When teaching the Common Core, teachers should:
Carefully connect the learning within and across
grades so that students can build new
understanding onto foundations built in previous
years.
Begin to count on solid conceptual understanding of
core content and build on it. Each standard is not a
new set of events, but an extension of previous
learning.
Shift Three: Rigor
The CCSSM require a balance of:
Solid conceptual understanding
Procedural skill and fluency
Application of skills in problem solving situations
This requires balanced intensity in time,
activities, and resources in pursuit of all three
Rigor
Place Value…
Why do we need rigor when we work
with place value concepts?
Hundreds, Tens, and Ones
In groups with teachers from different
grade levels, analyze the two
Hundreds, Tens, and Ones activities.
How does each provide…
Solid conceptual understanding
Procedural skill and fluency
Application of skills in problem solving
situations

Do these promote Conceptual
Understanding?

A pen for Aramis and Elise (Great Danes) is shown
below. Amy wants to add a safe place for her
Chihuahua to run around the great Danes (and not
get stepped on!). If she adds a fence that is 2½
feet from the current perimeter, how much fencing
will she need for the Chihuahua’s run?
The Chihuahua run
must be built 2½ feet
from the edge of the
Great Dane pen!

In pictures and words, show how you
used either mathematical practice 4
or 5 as you solved this task
(you might have to pull these out and
re-read )
An Experience with Students
The following slides are from DPI.
The Task
What would that look like…
With our students?
Step 1: Introduce/Review Standards for
Mathematical Practice # 4 and #5
Date:
Briefly describe how you will introduce/review Standards for Mathematical Practice #
4 and #5
Step 2: Apply Standards for Mathematical Practice # 4 and #5 to a math lesson.
Select a lesson that provides students the Briefly describe lesson chosen:
opportunity to choose appropriate tools
strategically and model with mathematics.
Toward the end of the lesson, ask students to illustrate how they used mathematical
practice #4 OR #5 in their work today.
Step 3: Bring illustrations to math planning.
As a team, choose 2 illustrations (one that shows a solid understanding and one that
shows minimal understanding). Send illustrations in to Amy and Marilyn (use
envelope provided).
