Chaffey High School
Algebra I
California State Framework for Algebra
Updated 13 September 2009

In 1999, the State of California
adopted and mandated standards that affect all public high school students
and their teachers. The Standards set forth the concepts, skills
and topics appropriate for students going on to the study of Geometry and
Algebra II and are required for high school graduation.
Originally, the state expected that each student graduating
in 2004 or later would pass the California High School Exit Examination in
mathematics and complete Algebra I in order to qualify for graduation. For
several years, these expectations were "modified" such that the
Algebra completion requirement did not take effect until
2005 and the California
High School Exit Examination (CAHSEE) requirement did not take effect until 2006.
Each year these expectations have been tweaked in some way as a result of legal
challenges. Since the 2006-2007 school year, all students graduating
from a California high school must pass the (CAHSEE), complete Algebra I and
complete another year of post-algebra mathematics (usually Geometry).
My intent is that our class meets and exceeds the Standards: that it
is taught in such a way as to adhere to both the spirit and the letter of those
Standards.
The following is a summary of
the Algebra Standards portion of the Mathematics Framework for California
Public Schools. The following items will be color coded according to
which module they are taught in Quarter A,
Quarter B, Quarter
C, Quarter D, or
not
explicitly taught. Those items not explicitly taught according to the Mastery
Mathematics model are included as time allows under current circumstances.
You should realize that, although a standard may be "addressed" by one of
the modules, there is no way to tell from this list whether that standard is
adequately covered in sufficient depth such that it contributes to a
students foundation for or desire to study Algebra II, Pre-calculus, Statistics,
or Calculus. In fact, most "standards" cannot be so covered
due of
the assessment and testing burden imposed on students and teachers.
-
Know and use the basic properties (including
closure) of the real numbers (including the
subsets of integers, rational numbers, and
irrational numbers).
-
Understand and know how to take the opposite, find the reciprocal,
take a square root,
and raise to a fractional power.
Understand and know how to use the rules of
exponents.
-
Understand absolute value
and how to solve absolute values equations and
inequalities.
-
Simplify and solve linear equations and inequalities
in one variable.
-
Know how to solve multi-step problems
(including
word problems),
involving linear equations
and linear inequalities
in one variable. Be able to explain each step.
-
Graph linear equations and find their
x-and
y-intercepts.
Graph linear inequalities.
-
Be able to tell if a point lies on a line, given
the equation of the line. Find linear equations by using the point-slope
formula.
-
Understand how slopes relate in parallel
and perpendicular lines. Find the equation of a line parallel to
and perpendicular to a given line through a given point.
-
Solve a system of two linear equations in two
variables (by substitution, elimination, and graphing). Solve a system of
inequalities by drawing its graph.
-
Add, subtract, multiply, and divide monomials and
polynomials.
Solve
problems (including word problems) by using these skills.
-
Be able to factor second- and simple
third-degree polynomials using GCF, difference of squares, perfect squares, and grouping methods.
-
Simplify fractions with polynomials
in the numerator and denominator by factoring both and reducing them to
lowest terms.
-
Add, subtract, multiply, and divide rational
expressions.
Solve challenging problems using these methods.
-
Be able to solve a quadratic equation by factoring
or by completing the square.
-
Be able to solve word problems (including rate
problems,
percent mixture problems,
etc).
-
Know what a relation and a function
are, and be able to tell if a given relation is a function.
-
Be able to find the domain and the range of a
function (by graph,
by set of ordered pairs,
or from an equation).
-
Be able to explain why a relation (defined by a
graph, by a set of ordered pairs,
or by an equation) is a function or not.
-
Know how to use the quadratic formula,
and how it comes from "completing the square."
-
Be able to use the quadratic formula
to find the roots of quadratic equations.
-
Be able to graph quadratic equations
and identify their roots as the x-intercepts of the graph.
-
Be able to tell using the discriminant whether the graph of a quadratic function will intersect the x-axis in
zero, one, or two points.
-
Solve physical problems (such as motion
under gravitational force) using quadratic equations.
-
Use and know simple aspects of logical argument
such as the difference between deductive and inductive reasoning, hypothesis and
conclusion, and use of counterexamples in proofs.
-
Use properties of the number system
to judge the validity of results, to justify procedural steps, and to prove/disprove
statements.
Items that I think should be standards
because they contribute greater depth and perspective to Algebra and the course
that follow (not included in Mastery Mathematics anyway):
-
Study skills appropriate to mathematical
development.
- Connecting
patterns to Algebra.
- Descriptive
probability and statistics.
- Comparing
and contrasting basic functions and their graphs (linear, quadratic, cubic,
absolute value, square root, reciprocal, and inverse square).
- Comparing
and contrasting transformations of the basic functions (horizontal and
vertical shifts, horizontal and vertical stretches, reflections and inverses).
- Solving
simple radical equations.
- History and
context appropriate to topics studied.
By statute, the standards are to be revisited and/or revised
every seven years. I hope that the next seven year cycle will see the
standards adjusted so that we shift away from a focus on enhanced test scores
for the mere sake of those scores to a better focus on what the standards intend
to accomplish in terms of how we position students for further study of and
appreciation of mathematics. If
a student has difficulty with any of the items listed above, it
is imperative that they immediately arrange tutoring sessions with Mr.
James or another person who is competent with algebra and acquainted with
these standards.
