CCSSI FOR MATHEMATICS
“STANDARDS OF PRACTICE”
Collegial Conversations
HIGH SCHOOL
Today’s Goal
 To explore the Standards for Content and
Practice for Mathematics
 Begin to consider how these new CCSS
Standards are likely to impact your classroom
practices
What are the Common Core State
Standards?
 Aligned with college and work expectations
 Focused and coherent
 Included rigorous content and application of
knowledge through high-order skills
 Build upon strengths and lessons of current state
standards
 Internationally benchmarked so that all students are
prepared to succeed in our global economy and society
 Research and evidence based
 State led- coordinated by NGA Center and CCSSO
Focus
• Key ideas, understandings, and skills are
identified
• Deep learning of concepts is emphasized
– That is, time is spent on a topic and on
learning it well. This counters the “mile wide,
inch deep” criticism leveled at most current
U.S. standards.
Benefits for States and Districts
•
•
•
•
Allows collaborative professional development based
on best practices
Allows development of common assessments and other
tools
Enables comparison of policies and achievement
across states and districts
Creates potential for collaborative groups to get more
economical mileage for:
– Curriculum development, assessment, and
professional development
Common Core Development
• Initially 48 states and three territories
signed on
• As of November 29, 2010, 42 states have
officially adopted
• Final Standards released June 2, 2010, at
www.corestandards.org
• Adoption required for Race to the Top
funds
Michigan’s Implementation Timeline
• Held October and November of 2010 rollouts
• District curricula and assessments that provide a
K-12 progression for meeting the MMC
requirements will require minimal adjustments to
meet CCSS
• Curriculum and assessment alignment in SY10-11
• Implementation SY11-12
• New assessment 2014-15 (Smarter Balanced
Assessment Consortium or SBAC – replaces MEAP
and MME)
Background
Responsibilities of States in the Consortium
Each State that is a member of the Consortium in 2014–
2015 also agrees to do the following:
 Adopt common achievement standards no later than the 2014–2015 school
year,
 Fully implement the Consortium summative assessment in grades 3–8 and
high school for both mathematics and English language arts no later than
the 2014–2015 school year,
 Adhere to the governance requirements,
 Agree to support the decisions of the Consortium,
 Agree to follow agreed-upon timelines,
 Be willing to participate in the decision-making process and, if a Governing
State, final decisions, and
 Identify and implement a plan to address barriers in State law, statute,
regulation, or policy to implementing the proposed assessment system and
address any such barriers prior to full implementation of the summative
assessment components of the system.
Technology Approach
SBAC Item Bank
• Partitioned into a secure item bank for
summative assessments and a non-secure
bank for the interim/benchmark assessments:
•
•
•
•
Traditional selected-response items
Constructed-response items
Curriculum-embedded performance events
Technology-enhanced items (modeled after
assessments in use by the U.S. military, the
architecture licensure exam, and NAEP)
HOW TO READ THE STANDARDS
Domains are large groups of related
standards. Standards from different
domains may sometimes be closely
related. Look for the name with the code
number on it for a Domain.
Common Core Format
Clusters are groups of related standards.
Standards from different clusters may
sometimes be closely related, because
mathematics is a connected subject.
• Clusters appear inside domains.
Standards
define what

should be

able to understand and be able to do –
part of a cluster.
They are content statements. An example content statement
is: “Use the structure of an expression to identify ways to
rewrite it. For example, see x4 – y4 as (x2)2 – (y2)2, thus
recognizing it as a difference of squares that can be factored
as (x2 – y2)(x2 + y2)”.
•Progressions of increasing complexity from grade to grade
Common Core - Clusters
• May appear in multiple grade levels in the K-8
Common Core. There is increasing development
as the grade levels progress
• What students should know and be able to do
at each grade level
• Reflect both mathematical understandings and
skills, which are equally important

6. Apply and extend previous understandings of multiplication

Statistics and Probability, Grade 6
Develop understanding of statistical variability
•
•
•
Recognize a statistical question as one that anticipates variability in the
data related to the question and accounts for it in the answers. For
example, “How old am I?” is not a statistical question, but “How old are
the students in my school?” is a statistical question because one
anticipates variability in students’ ages.
Understand that a set of data collected to answer a statistical question
has a distribution which can be described by its center, spread, and
overall shape.
Recognize that a measure of center for a numerical data set summarizes
all of its values with a single number, while a measure of variation
describes how its values vary with a single number.
Algebra, Grade 8

increasing developmental standards as the
grade levels progress

Common Core - Standards
• Content statements
• Progressions of increasing complexity from
grade to grade
– In high school, this may occur over the course
of one year or through several years
HS Pathways
1.) Traditional (US) – 2 Algebra, Geometry and Data, probability
and statistics included in each course
2.) International (integrated) three courses including number ,
algebra, geometry, probability and statistics each year
3.) Compacted version of traditional – grade 7/8 and algebra
completed by end of 8th grade
4.) Compacted integrated model, allowing students to reach
Calculus or other college level courses
High School Pathways
• The CCSS Model Pathways are NOT required. The two
sequences are examples, not mandates
• Two models that organize the CCSS into coherent,
rigorous courses
• Four years of mathematics:
– One course in each of the first two years
– Followed by two options for year 3 and a variety of relevant courses for
year 4
• Course descriptions
– Define what is covered in a course
– Are not prescriptions for the curriculum or pedagogy

• Pathway B: Typically seen internationally that
consists of a sequence of 3 courses each of which
treats aspects of algebra, geometry and data,
probability, and statistics.

High School - Modeling
• Linking mathematics and statistics to everyday

mathematics and statistics
• Examples: pg 72
Modeling
Modeling has no specific domains, clusters
or standards. Modeling is included in the
other conceptual categories and marked
with a asterisk.
Modeling
Modeling links classroom mathematics and
statistics to everyday life, work, and
decision-making. Technology is valuable in
modeling.
A model can be very simple, such as writing
total cost as a product of unit price and
number bought, or using a geometric
shape to describe a physical object.
Modeling

players at a club with 4 tables, where each
player plays against each other player.
• Analyzing stopping distance for a car.
• Modeling savings account balance,
bacterial colony growth, or investment
growth.

“The Standards for Mathematical Practice describe varieties of expertise that
mathematics educators at all levels should seek to develop in their students.
These practices rest on important “processes and proficiencies” with
longstanding importance in mathematics education.” CCSS, 2010
Standards for Mathematical Practice

Standards of Mathematical
Practice
1. Choose a partner at your table and “Pair Share”
the Standards of Practice between you and your
partner.
2. When you and your partner feel you understand
generally each of the standards, discuss the
following question:
What implications might the standards
of practice have on your classroom?

Transition Planning
Next Steps:
• Alignment of CCSS with curriculum
• Gap analysis (content and skills that vary from
the MEAP and MME)
• What instructional practices will facilitate the
transition?
• What new assessment strategies will be
needed?
• Professional development needs?
Transition Planning
• Gather in teams from your schools and discuss
– What are your immediate needs as a classroom teacher
being asked to implement the CCSS?
– What professional development is needed?
– What initial gaps come to mind and how do you address
these gaps?
– As a school team, look at the eight Standards for
Mathematical Practice. What do they look like? Sound
like? What will students need in order to implement them?
What will teachers need? What are the implications for
assessment and grading?
