Title: Common Core State Standards for Mathematics: Focus at Grade 5
1Common Core State Standards for Mathematics
Focus at Grade 5
- Professional Development Module
2The CCSS Requires Three Shifts in Mathematics
- Focus Focus strongly where the standards focus.
- Coherence Think across grades, and link to major
topics - Rigor In major topics, pursue conceptual
understanding, procedural skill and fluency, and
application
3Focus
- The two major evidence-based principles on which
the standards are based are focus and coherence. - Focus is necessary so that students have
sufficient time to think, practice, and integrate
new ideas into their growing knowledge structure.
- Focus is also a way to allow time for the kinds
of rich classroom discussion and interaction that
support the Standards for Mathematical Practice.
4Shift 1 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 on what is emphasized in the
standards, so that students gain strong
foundations.

6Focus
- Focus is critical to ensure that students learn
the most important content completely, rather
than succumb to an overly broad survey of
content. Focus shifts over time, as seen in the
following - In grades K-5, the focus is on the addition,
subtraction, multiplication, and division of
whole numbers fractions and decimals with a
balance of concepts, skills, and problem solving.
Arithmetic is viewed as an important set of
skills and also as a thinking subject that, done
thoughtfully, prepares students for algebra.
Measurement and geometry develop alongside number
and operations and are tied specifically to
arithmetic along the way.
7Key Areas of Focus in Mathematics
Grade Focus Areas in Support of Rich Instruction and Expectations of Fluency and Conceptual Understanding
K2 Addition and subtraction - concepts, skills, and problem solving and place value
35 Multiplication and division of whole numbers and fractions concepts, skills, and problem solving
6 Ratios and proportional reasoning early expressions and equations
7 Ratios and proportional reasoning arithmetic of rational numbers
8 Linear algebra
8Focus
- Move away from "mile wide, inch deep" curricula
identified in TIMSS. - Learn from international comparisons.
- Teach less, learn more.
- Less topic coverage can be associated with
higher scores on those topics covered because
students have more time to master the content
that is taught.

12Examples of Opportunities for In-Depth Focus
- 5.NBT.1 The extension of the place value system
from whole numbers to decimals is a major
intellectual accomplishment involving
understanding and skill with base-ten units and
fractions. - 5.NBT.6 The extension from one-digit divisors to
two-digit divisors requires care. This is a major
milestone along the way to reaching fluency with
the standard algorithm in grade 6 (6.NS.2). - 5.NF.2 When students meet this standard, they
bring together the threads of fraction
equivalence (grades 35) and addition and
subtraction (grades K4) to fully extend addition
and subtraction to fractions. - 5.NF.4 When students meet this standard, they
fully extend multiplication to fractions, making
division of fractions in grade 6 (6.NS.1) a near
target. - 5.MD.5 Students work with volume as an attribute
of a solid figure and as a measurement quantity.
Students also relate volume to multiplication and
addition. This work begins a progression leading
to valuable skills in geometric measurement in
middle school.
13Example of Opportunities for Connecting
Mathematical Content and Mathematical Practices
- Mathematical practices should be evident
throughout mathematics instruction and connected
to all of the content areas addressed at this
grade level. Mathematical tasks (short, long,
scaffolded, and unscaffolded) are an important
opportunity to connect content and practices. The
example below shows how the content of this
grade might be connected to the practices. - When students break divisors and dividends into
sums of multiples of base-ten units (5.NBT.6),
they are seeing and making use of structure
(MP.7) and attending to precision (MP.6).
Initially for most students, multi-digit division
problems take time and effort, so they also
require perseverance (MP.1) and looking for and
expressing regularity in repeated reasoning
(MP.8).
14Group Discussion
- Shift 1 Focus strongly where the Standards
focus. - In your groups, discuss ways to respond to the
following question, Why focus? Theres so much
math that students could be learning, why limit
them to just a few things?
15Engaging with the shift What do you think
belongs in the major work of each grade?
Grade Which two of the following represent areas of major focus for the indicated grade? Which two of the following represent areas of major focus for the indicated grade? Which two of the following represent areas of major focus for the indicated grade?
K Compare numbers Use tally marks Understand meaning of addition and subtraction
1 Add and subtract within 20 Measure lengths indirectly and by iterating length units Create and extend patterns and sequences
2 Work with equal groups of objects to gain foundations for multiplication Understand place value Identify line of symmetry in two dimensional figures
3 Multiply and divide within 100 Identify the measures of central tendency and distribution Develop understanding of fractions as numbers
4 Examine transformations on the coordinate plane Generalize place value understanding for multi-digit whole numbers Extend understanding of fraction equivalence and ordering
5 Understand and calculate probability of single events Understand the place value system Apply and extend previous understandings of multiplication and division to multiply and divide fractions
6 Understand ratio concepts and use ratio reasoning to solve problems Identify and utilize rules of divisibility Apply and extend previous understandings of arithmetic to algebraic expressions
7 Apply and extend previous understandings of operations with fractions to add, subtract, multiply, and divide rational numbers Use properties of operations to generate equivalent expressions Generate the prime factorization of numbers to solve problems
8 Standard form of a linear equation Define, evaluate, and compare functions Understand and apply the Pythagorean Theorem
Alg.1 Quadratic inequalities Linear and quadratic functions Creating equations to model situations
Alg.2 Exponential and logarithmic functions Polar coordinates Using functions to model situations
16Examples of Key Advances from Grade 4 to Grade 5
- In grade 5, students will integrate decimal
fractions more fully into the place value system
(5.NBT.14). By thinking about decimals as sums
of multiples of base-ten units, students begin to
extend algorithms for multi-digit operations to
decimals (5.NBT.7). - Students use their understanding of fraction
equivalence and their skill in generating
equivalent fractions as a strategy to add and
subtract fractions, including fractions with
unlike denominators.
17Example from SBA p.16-17
- Students apply and extend their previous
understanding of multiplication to multiply a
fraction or whole number by a fraction (5.NF.4).
They also learn the relationship between
fractions and division, allowing them to divide
any whole number by any nonzero whole number and
express the answer in the form of a fraction or
mixed number (5.NF.3). And they apply and extend
their previous understanding of multiplication
and division to divide a unit fraction by a whole
number or a whole number by a unit fraction.13 - ?
18Content Emphases by Cluster Grade Five
Key Major Clusters Supporting Clusters
Additional Clusters
19Examples of Opportunities for Connections among
Standards, Clusters or Domains
- The work that students do in multiplying
fractions extends their understanding of the
operation of multiplication. For example, to
multiply a/b x q (where q is a whole number or a
fraction), students can interpret a/b x q as
meaning a parts of a partition of q into b
equal parts (5.NF.4a). This interpretation of the
product leads to a product that is less than,
equal to or greater than q depending on whether
a/b lt 1, a/b 1 or a/b gt 1, respectively
(5.NF.5). - Conversions within the metric system represent an
important practical application of the place
value system. Students work with these units
(5.MD.1) can be connected to their work with
place value (5.NBT.1).
20Task Matching Clusters and Critical Areas
- Read through the cluster headings for your
grade. - Discuss each cluster heading and decide which
critical area it falls within. - Cut and paste the cluster heading on the page
with the appropriate critical area.
21Matching Clusters with Critical Areas Small
Group Discussion
- Were you able to match each cluster heading with
one of the critical areas? How did you decide
which area to place it under? What challenges did
you have? - How do the cluster headings help clarify the
concepts in the critical areas?
22The Standards
- Find the critical areas for your grade.
- Find the cluster headings for your grade.
- Find and read the standards that fall under each
cluster heading. - Write down two first impressions you have about
the standards. - Write down two questions you have about the
standards.
23Reflection Journal
- How have the cluster headings helped clarify
the important mathematical concepts in the
critical areas? - How will you use this information to guide your
curriculum and instruction? What changes will you
make? - What questions do you still have about the
standards?
24Your Assignment
- Choose one of the critical areas to investigate
back in the classroom - Find a lesson in your curriculum addressing the
critical area - What evidence will convince you that students
understand this concept? - What common misconceptions do students have when
studying this critical area? - What challenges have you had in teaching these
critical area concepts?
