QUESTION 1: CRITICAL AREAS (1e, 2d, 4d)
Not all of the content in a given grade is emphasized equally in the standards. Some clusters require
greater emphasis than the others 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. In
addition, 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.
What are the critical areas at each grade level (K-8)?

QUESTION 3: SUPPORTING CLUSTERS (1e)
The Common Core State Standards for Mathematics denote content emphasis using 3 qualifying levels:
 Major Clusters (green)
 Supporting Clusters (blue)
 Additional Clusters (yellow)
Supporting Clusters work to support the Major Work of the grade. Describe how the Supporting
Cluster (5.MD.1) reinforces the Major Cluster (5.NBT.7).
5.NBT.A.7 Add, subtract, multiply, and divide decimals to hundredths, using concrete models or
drawings and strategies based on place value, properties of operations, and/or the relationship
between addition and subtraction; relate the strategy to a written method and explain the reasoning
used.
5.MD.B.1 Convert among different-sized standard measurement units within a given measurement
system (e.g., convert 5 cm to 0.05 m), and use these conversions in solving multi-step, real world
problems.

Common Core State Standards in Mathematics Pre-Test
QUESTION 4: RIGOR (1e)
In the CCSSM, rigor is defined in the major topics as the pursuit conceptual understanding, procedural
skill and fluency, and application. Certain standards complement procedural skills, conceptual
understandings of specific content, or expect students to apply and extend a concept to a real world or
mathematical problem solving scenario. The “verbs” within each standard provide cues indicating the
aspect of rigor being addressed. For example, the standard below addresses a procedural skill by which
students should support their calculations using various representations: equations, rectangular arrays,
and/or area models.
CCSS.Math.Content.4.NBT.B.5 Multiply a whole number of up to four digits by a one-digit whole
number, and multiply two two-digit numbers, using strategies based on place value and the properties
of operations. Illustrate and explain the calculation by using equations, rectangular arrays, and/or area
models.

In tasks assessing Conceptual Understanding
- the assessed concept should be central to the task
- the necessary computational skill should be fairly low
- the task should be easy to solve if the student understands the concept
- the tasks do not reside in an application

In tasks assessing Procedural Skill & Fluency
- students are explicitly required to perform a calculation by manipulating numbers and operations
to derive an answer (with precision and accuracy)

In tasks assessing Application
- students are expected to use appropriate concepts and skills
- opportunities should exist for students to apply math concepts to real world & mathematical
problems
Indicate whether each of the standards explicitly call for conceptual understanding, procedural skill
and fluency, or application.

CCSS.Math.Content.4.NF.B.3a Understand addition and subtraction of fractions as joining and
separating parts referring to the same whole.

CCSS.Math.Content.4.NF.B.3c Add and subtract mixed numbers with like denominators, e.g.,
by replacing each mixed number with an equivalent fraction, and/or by using properties of
operations and the relationship between addition and subtraction.

CCSS.Math.Content.4.NF.B.3d Solve word problems involving addition and subtraction of
fractions referring to the same whole and having like denominators, e.g., by using visual
fraction models and equations to represent the problem.

QUESTION 5: MULTIPLE REPRESENTATIONS (2a)
Promoting a culture of high expectations for all students is a fundamental goal of the Common Core
State Standards. In order to participate with success in the general curriculum, students with
disabilities, as appropriate, may be provided additional supports based on the principles of Universal
Design for Learning (UDL) - which foster student engagement by presenting information in multiple
ways and allowing for diverse avenues of action and expression.
Multiple Representations allow teachers to present content in multiple modalities to support flexible
thinking. These frameworks go beyond concrete representation (e.g. manipulatives) to promote the
realistic representation of concepts addressed in multiple settings.
Below is an example of a Multiple Representations Framework that supports CCSS Math Cluster 7.NS.A
Apply and extend previous understandings of addition and subtraction to add and subtract rational
numbers; represent addition and subtraction on a horizontal or vertical number line diagram.
How does each representation (Concrete, Pictorial, and Abstract) support the cluster?

Adding Integers
Addition is modeled as putting a second vector’s tail at the first
vector’s head and finding where the second vector’s head extends
to.
3 + -4 = -1
Subtracting Integers
Subtraction can be thought of as comparing the two vectors p, and
q, by putting both tails together (starting each from zero) and
asking the question: “How would one extend a vector from the head
of p to the head of q?” The length and direction of that vector would
be the result of the subtraction.
3 - -4 = 7

ABSTRACT REPRESENTATIONS
p – q = p + (-q)
Applying Properties of Numbers
p - -q = p + q

QUESTION 8: INSTRUCTION and PLANNING (1e, 1f)
Although the CCSSM do not explicitly reference instructional delivery, certain practices, such as
strategic planning, are essential to ensure that instruction is well aligned to the intended objective(s).
Key planning strategies encourage teachers to

Study the standard to highlight key elements

Look at aligned assessment items to help plan with the end in mind (i.e. mastery level
problems, problems embedding the practices, problems assessing all aspects of rigor)

Select tasks that align well to the day’s objective (focusing more so on conceptual
understandings initially )

Solve the problems in advance

Consider various entry points to determine which will inform the day’s objective

Consider potential student errors and misconceptions
Which of the 6 planning strategies, if any, are evident in the lesson outlined on the next page?

Common Core State Standards in Mathematics Pre-Test
A Grade 6 teacher asks students to determine the number of shaded squares border this 10 by 10 figure,
(without counting). Her goal is to have students ‘apply and extend their previous understandings of
arithmetic to algebraic expressions’.
The teacher takes a moment, in a whole group format, to review some of the anticipated and likely
errors that students would make. She then captures expressions that students used to generate the
correct answer. As an extension to the activity, the teacher asks students to use the captured student
responses (below) to generate numerical expressions for a 6 by 6 figure, then an algebraic expression
for an n by n figure.

RATIOS & PROPORTIONAL REASONING FRAMEWORK: TEACHER NOTES
UNDERSTANDING RATIOS
UNIT RATE
REPRESENTATIONS
A ratio is a pair of non-negative numbers, A : B, which are not
both 0 associating two (or more) quantities.
A units
B units
Some authors distinguish ratios from rates, using the term
“ratio” when units are the same and “rate” when units are
different; others use ratio to encompass both kinds of
situations. Standards use ratio in the second sense, applying
it to situations in which units are the same as well as to
situations in which units are different. Relationships of two
quantities in such situations may be described in terms of
ratios, rates, percents, or proportional relationships.
Ratios have associated rates, expressed as the unit
rate.
A
B
The unit rate is the numerical part of the rate; the
“unit” in “unit rate” is often used to highlight the 1 in
“for each 1” or “for every 1.”

Equivalent ratios arise by multiplying each measurement in a
ratio pair by the same positive number.
Proportional relationships involve collections of pairs of
measurements in equivalent ratios.
A proportion is an equation stating that two ratios are
equivalent.
Equivalent ratios have the same unit rate.
cA = A
cB
B
A proportional relationship is described by an equation
of the form y= kx, where k is a positive constant, often
called a constant of proportionality. The constant of
𝐵
proportionality, k, is equal to the value . The graph of
𝐴
a proportional relationship lies on a ray with endpoint
at the origin.

 3 for every 2; e.g., 3 cups of flour for
every 2 eggs; 3 meters in 2 seconds
 3 out of every 5
 3 parts to 2 parts
Notation for ratios can include the
 Use of a colon, as in 3 : 2
 Use of quotient, as in 3/2
NOTE: Although it is traditional to move students quickly to solving proportions by setting up an equation, the Standards do not require this method in
14
Grade 6. There are a number of strategies for solving problems that involve ratios.
