It’s Not the Same Old
Algebra and Geometry

Investigate/Explore - Students will be given situations in which they will be
asked to look for patterns or relationships between elements within the setting.
Discover - Students will make note of possible patterns and generalizations
that result from investigation/exploration.
Conjecture - Students will make an overall statement, thought to be true, about
the new discovery.
Reasoning - Students will engage in a process that leads to knowing
something to be true or false.
Argument - Students will communicate, in verbal or written form, the reasoning
process that leads to a conclusion. A valid argument is the end result of the
conjecture/reasoning process.
Justify/Explain - Students will provide an argument for a mathematical
conjecture. It may be an intuitive argument or a set of examples that support
the conjecture. The argument may include, but is not limited to, a written
paragraph, measurement using appropriate tools, the use of dynamic software,
or a written proof.
Proof - Students will present a valid argument, expressed in written form,
justified by axioms, definitions, and theorems.
Apply - Students will use a theorem or concept to solve an algebraic or
numerical problem.

Integrated Algebra
In implementing the Algebra process and content performance
indicators, it is expected that students will identify and justify
mathematical relationships. The intent of both the process
and content performance indicators is to provide a variety
of ways for students to acquire and demonstrate
mathematical reasoning ability when solving problems.
Local curriculum and local/state assessments must support
and allow students to use any mathematically correct
method when solving a problem.
Throughout this document the performance indicators use the
words investigate, explore, discover, conjecture, reasoning,
argument, justify, explain, proof, and apply. Each of these terms
is an important component in developing a student’s
mathematical reasoning ability.
Crosswalks To Algebra Other than from Math A
From Middle School:
A.N.5 - Solving Algebraic problems involving fractions,
decimals, percents (decrease/increase and discount), and
proportionality/direct variation
Math 8 does not use the term “direct variation”.
A.N.6 - Evaluating expressions involving factorial(s),
absolute value(s), and exponential expression(s)
Factorials and absolute value in grade 7
Math 8 handles expressions with exponents.
A.A.9 - Analyze and solve verbal problems that involve
exponential growth and decay Start from scratch!
A.A.21 - Verifying a value as a solution to a linear equation
or inequality in one variable
A.A.45 - Application of Pythagorean theorem (grade 7)
A.M.1 - Calculations of rate (grade 7)
Crosswalks To Algebra Other than from Math A
From Math B
A.G.3 - Determine when a relation is a function
A.G.5 - How coefficient change in a function effects its graph
(Associate with graphs of parabolas. Use the calculator.)
A.S.3 - Determine when collected data or display may be biased
A.S.4 - Compare and contrast the appropriateness of different
measures of central tendency for a given data set
A.S.8 - Line of best fit for a scatter plot and its equation
(The line drawn depends on the 2 points chosen to define
the line. Or.. Stat..calc…4:LinReg(ax + b))
A.S.15 - Identify and describe sources of bias and its effect,
drawing conclusion from data
A.S.17 - Use a reasonable line of best fit to make a prediction
involving interpolation or extrapolation
Crosswalks To Algebra- New to 2005 Standards
A.A.3 - Difference between an Algebraic expression and an
Algebraic equation
(Now a Middle School topic: Is there an equal sign?)
A.A.28 - Relation between roots and factors of a quadratic
equation (Not really new)
A.A.29 - Set builder notation and/or interval notation to represent
the elements of a set
A.A.30 - Complement of a set
A.A.31 – Intersection of sets
A.A.32 - Slope as a rate of change (not really new)

Riverside Test Publishing has overall responsibility
for the Regents exams for the next few years. New
York State teachers are the question writers, trained
by Riverside. Riverside is responsible for final
format.
State Ed Update:
For standard-setting the new exams, the Department
will use the same processes that were used for the
Grades 3 – 8 Testing Program, including standard
setting AFTER the test has been administered using
operational testing data (rather than field testing
data).

Geometry
There is no other school mathematics course that offers
students the opportunity to act as mathematicians. Within this
course, students will have the opportunity to make conjectures
about geometric situations and prove in a variety of ways, both
formal and informal, that their conclusion follows logically from
their hypothesis.
The variety of approaches to verification and proof is what
gives curriculum developers and teachers the flexibility to
adapt strategies to address these performance indicators in a
manner that meets the diverse needs of our students. Local
curriculum and local/state assessments must support and
allow students to use any mathematically correct method
when solving a problem.
It is intended that students will use the traditional tools of compass
and straightedge as well as dynamic geometry software that
models these tools more efficiently and accurately, to assist in
these investigations.

G.G.6 If a line is perpendicular to a plane, then any line
perpendicular to the given line at its point of
intersection with the given plane is in the given plane
G.G.7 If a line is perpendicular to a plane then every
plane containing the line is perpendicular to the given

parallel.
GG.10 The lateral edges of a prism are congruent and

Algebra 2 and Trigonometry
This course is a continuation and extension of the two courses
that preceded it. While developing the algebraic techniques that
will be required of those students that continue their study of
mathematics, this course is also intended to continue
developing alternative solution strategies and algorithms.
For example, technology can provide to many students the
means to address a problem situation to which they might
not otherwise have access. In implementing the Algebra 2 and
Trigonometry process and content performance indicators, it is
expected that students will identify and justify mathematical
relationships, formally and informally. The intent of both the
process and content performance indicators is to provide a
variety of ways for students to acquire and demonstrate
mathematical reasoning ability when solving problems. Local
curriculum and local/state assessments must support and
