Standard 3
The Three Components
•Conceptual Understanding consists of those
relationships constructed internally and connected to
already existing ideas.
•Procedural Fluency is the skill in carrying out
procedures flexibly, accurately, efficiently, and
appropriately.
•Problem Solving is the ability to formulate,
represent, and solve mathematical problems.

Work with two other students to solve
the following problem:
Cameron received a set of four grades.
If the average of the first two grades
is 50, the average of the second and
third grades is 75, and the average of
the third and fourth grades is 70, then
what is the average of the first and
fourth grades?
The Five Content Strands
Performance Indicators which:
• define a broad range of content knowledge
that students must master
• are taught in an integrated manner
• engage students in construction of knowledge
• integrate conceptual understanding and
problem solving
• should not be viewed as a checklist of skills
void of understanding and application
Number Sense and Operations
Strand
Students will:
•understand numbers, multiple ways of
representing numbers, relationships among
numbers, and number systems;
•understand meanings of operations and
procedures, and how they relate to one
another;
•compute accurately and make reasonable
estimates.
Algebra Strand
Students will:
•represent and analyze algebraically a wide
variety of problem solving situations;
•perform algebraic procedures accurately;
•recognize, use, and represent algebraically
patterns, relations, and functions.
Geometry Strand
Students will:
•use visualization and spatial reasoning to
analyze characteristics and properties of
geometric shapes;
•identify and justify geometric relationships,
formally and informally;
•apply transformations and symmetry to
analyze problem solving situations;

problem solving situations.
Measurement Strand
Students will:
•determine what can be measured and how,
using appropriate methods and formulas;

measurements.
Statistics and Probability Strand
Students will:
•collect, organize, display, and analyze data;
•make predictions that are based upon data
analysis;
•understand and apply concepts of probability.
The Five Process Strands
Performance Indicators which:
• highlight ways of acquiring and using content
knowledge
• give meaning to mathematics as a discipline
rather than a set of isolated skills
• engage students in mathematical content as
they solve problems, reason mathematically,
prove mathematical relationships, participate
in mathematical connections, and model and
represent mathematical ideas
Problem Solving Strand
Students will:
•build new mathematical knowledge through
problem solving;
•solve problems that arise in mathematics and
in other contexts;
•apply and adapt a variety of appropriate
strategies to solve problems;
•monitor and reflect on the process of
mathematical problem solving.
Reasoning and Proof Strand
Students will:
•recognize reasoning and proof as
fundamental aspects of mathematics;
•make and investigate mathematical
conjectures;
•develop and evaluate mathematical
arguments and proofs;
•select and use various types of reasoning and
methods of proof.
Communication Strand
Students will:
•organize and consolidate their mathematical
thinking through communication;
•communicate their mathematical thinking
coherently and clearly to peers, teachers, and
others;
•analyze and evaluate the mathematical
thinking and strategies of others;
•use the language of mathematics to express
mathematical ideas precisely.
Connections Strand
Students will:
•recognize and use connections among
mathematical ideas;
•understand how mathematical ideas
interconnect and build on one another to
produce a coherent whole;
•recognize and apply mathematics in contexts
outside of mathematics.
Representation Strand
Students will:
•create and use representations to organize,
record, and communicate mathematical ideas;
•select, apply, and translate among
mathematical representations to solve
problems;
•use representations to model and interpret
physical, social, and mathematical
phenomena.

Integrated Algebra
Some Major

Sets
•Set-Builder Notation and Interval
Notation
•Complement of a Subset of a
Given Set
•Intersection and/or Union of Sets
Given that U={1,2,3,4,5} and
A={3,4,5} list the elements in the
complement of set A, Ā.
When A= {3,4,5} and B = {4,5,6,7},
find: AB and AB

•Qualitative or Quantitative
•Univariate or Bivariate
•Bias, Including Sources
•Evaluation of Reports or Graphs
Experimental Design
Appropriateness of Data Analysis

Data (continued):
•Percentile Rank of Item in Data Set
First, Second, Third Quartiles
•Variables: Correlation But Not Causation
•Linear Transformations Affect Mean,
Median, Mode
•Scatter Plots, Line of Best Fit
Identify the following data sets as
either qualitative or quantitative:
•Presidents and their places of birth.
•Percent of persons living in poverty.
•Number of votes cast in the 2004
presidential election.
•Favorite places for vacation.
•Baseball players and the position they
play.
State if the following data sets are
univariate or bivariate:
•Three-year rate of return for various
mutual funds.
•Relationship between per capita gross
domestic product and the life
expectancy of residents of a country.
•Gestation period of an animal and the
animal’s life expectancy.
•The pulse rate of eight randomly
selected individuals after jogging for
one minute.
A research company wanted to obtain data on
what is watched on television by community
members who are 18 years old and older. Their
research company made random telephone calls
to homes in the community. The telephone calls
resulted in:
•An inability to reach a person in 53% of the
homes called.
•The exclusion of non-telephone homes in the
community.
•Those surveyed were 72% male and 28%
females.
Explain how each of the three factors above
could create a bias in the survey results.
