7th Grade Math Curriculum Map
Introduction
This document contains all mandated 2010 Arizona Mathematical Standards for 7th grade mathematics. The standards have been organized into
units and clusters. The units represent the major domain under which the identified standards fall. The cluster represents the collection of similar
concepts within the larger domain. Within these units and clusters the performance objectives have been sequenced to represent a logical progression
of the content knowledge. It is expected that all teachers follow the sequence of units and clusters as described in the following document.

Organization
Approximate Time
Approximate times are based on a 60-minute instructional session for grades 6-8. All units and clusters must be taught prior to the 2013 AIMS
assessment.

Essential Questions
Essential Questions are to be posed to the students at the beginning of the cluster and revisited throughout the cluster. They are designed to facilitate
conceptual development of the content and can be used as a tool for making connections, higher order thinking and inquiry. The students should be
able to answer these on their own by the end of the cluster.

Big Ideas
Big Ideas are the essential understandings that are critical for students’ learning. These are the enduring understandings we want students to carry
with them from grade level to grade level. Answering the Essential Questions is indicative of a student mastering the Big Idea, however they are not
always synonymous. Thus, in cases that the answer to the Essential Question does not include all components of the Big Idea, the Big Idea (for teacher
use) has been provided in italics.

Common Misconceptions
These are common misunderstandings students bring to the learning process. Being aware of such misconceptions allows us to plan for them during
instruction.

Content Standards and Mathematical Practices
This document has been organized by content standards and mathematical practices. The content standards are those that represent knowledge
specific to the mathematical standard (The five domains). The mathematical practices 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. The content standards and mathematical standards have been paired to represent possible combinations of content standards
with mathematical practices. As described in the Arizona state standards, the content standards are not intended to be taught in isolation; thus, the
pairing of these standards provides a possible context for teaching these standards. Each time, the performance objective should be taught to a
deeper level of understanding and/or should be connected to the other standards in the cluster.

Common Core/Cross Curricular
The standards in the Common Core/Cross Curricular column represent possible reading, writing, math and language standards that can be reinforced
or taught through the mathematical content standards with which they are paired.

Priority
With input from grade level teachers, standards have been prioritized in two ways. The content standards have been prioritized using a three-point
scale. Essential standards represent those that are heavily weighted on state/national exams, foundational, and/or applicable in multiple contexts.
Important standards are those that are applicable in many contexts and less heavily weighted on state/national exams. Useful standards are those
with the least weight on state/national exams and are likely only useful in a specific context. This is denoted in the priority column with the codes E
(essential), I (important) and U (useful). This label applies to the content standards only. The skill/process standards that are a priority for this
grade level are highlighted in blue and are expected to be mastered at this grade level.

Key Vocabulary
The key vocabulary that should be taught for each of the performance objectives is listed under key vocabulary. These vocabulary words are coded
as tier one (1), tier two (2) or tier three (3). Tier one words are those that are very common and should not be explicitly taught. Tier two words are
high utility words that can be used across content areas or contexts. Tier three words are content specific words.

Resources
The two types of resources listed are the Web Resources resources and the Core Resources. All are suggestions that teachers may use to support
instruction. They are aligned to the standards listed in the same row. The web resources are useful Internet links that can be used for the teacher’s
edification prior to instruction or as a tool during instruction. The core resources are suggested pages from the adopted texts.

Unit/Cluster Project
The Unit/Cluster Projects are possible projects that teachers can use to support students in making connections, critical thinking, higher order thinking,
and/or spiraling curriculum. Unit projects support standards from all clusters within a unit while cluster project support the standards in a particular
cluster. While it is not required that a teacher do a project with every unit or cluster these resources will support project-based instruction and
practice should the teacher choose to implement them.

Assessment
The assessment section of the map has been left blank for teachers to plan the dates that they will give a formative assessment for the cluster. It is
expected that each cluster be assessed using a common formative assessment.

Other
Standards may appear more than once. Each time they should be taught within the context of the cluster and/or revisited to a deeper level of
knowledge. Underlined segments of a standard indicate an additional piece of the standard that was likely not covered in previous clusters.
[Brackets] will occasionally appear though out the document and indicate clarification of the Standard. Bracketed information is not a part of the
standard itself.

Essential Questions Big Ideas

 Why is it important to know proportions?  Students will understand that proportional

relationships are used to solve real-world situation.

proportional that one varies directly with another. As

the rate of one quantity changes, the other quantity

the mean height of players on the ET07-S1C3-01
soccer team, about twice the ET07-S1C3-02

 Students will understand that the probability that an

even will occur is equal to the number of favorable

outcome divided by the total number of outcomes.

 Students will understand that a sample space is a

diagram of all possible outcomes for a given

situation.


7.SP.5. Understand that the probability 7.MP.4. 6-8.WHST.1b Certain
of a chance event is a number between 7.MP.5. SS07-S5C1-04 Equally likely
0 and 1 that expresses the likelihood 7.MP.6. ET07-S1C3-01 Favorable outcome
of the event occurring. Larger numbers 7.MP.7. ET07-S1C3-02 Impossible
indicate greater likelihood. A Likely
probability near 0 indicates an unlikely Possible outcome
event, a probability around ½ Probability
indicates an event that is neither Simple event
unlikely nor likely, and a probability Unlikely

7.SP.8. Find probabilities of compound 7.MP.1. 6-8.WHST.2d Compound event
events using organized lists, tables, 7.MP.2. ET07-S1C2-01 Sample space

a. Understand that, just as with simple 7.MP.7. SC07-S1C4-03
events, the probability of a compound 7.MP.8. SC07-S1C4-05
event is the fraction of outcomes in the SC07-S1C2-02
sample space for which the compound SC07-S1C2-03
event occurs.

b. Represent sample spaces for
compound events using methods such as
organized lists, tables and tree
diagrams. For an event described in
everyday language (e.g., “rolling
double sixes”), identify the outcomes in
the sample space that compose the
event.

c. Design and use a simulation to
generate frequencies for compound
events. For example, use random digits
as a simulation tool to approximate the
answer to the question: If 40% of
donors have type A blood, what is the
probability that it will take at least 4
donors to find one with type A blood?

 Students will understand that the more trials used in

a. Develop a uniform probability model by ET07-S4C2-01
assigning equal probability to all outcomes, ET07-S4C2-02
and use the model to determine ET07-S6C1-03
probabilities of events. For example, if a ET07-S6C2-03
student is selected at random from a class,
find the probability that Jane will be selected
and the probability that a girl will be selected.

b. Develop a probability model (which may
not be uniform) by observing frequencies in
data generated from a chance process. For
example, find the approximate probability
that a spinning penny will land heads up or
that a tossed paper cup will land open-end
down.

Do the outcomes for the spinning penny
appear to be equally likely based on the
observed frequencies?
