Sample Scope and Sequence for Algebra II for the Common Core State Standards for Mathematics
In Algebra I, students have already begun their study of algebraic concepts. They have used equations, tables, and graphs to describe
relationships between quantities, with a particular focus on linear, quadratic, and exponential functions and equations.
The Algebra II course outlined in this scope and sequence document begins with connections back to that earlier work, efficiently reviewing
algebraic and statistical concepts that students have already studied while at the same time moving students forward into new concepts.
Students expand their library of functions to include polynomial functions, logarithmic functions, rational functions, and trigonometric
functions. With a larger library of functions, students increase their ability to model situations, make predictions and answer questions about
the situation.
This scope and sequence assumes 160 days for instruction, divided among 13 units. The units are sequenced in a way that we believe best
develops and connects the mathematical content described in the Common Core State Standards for Mathematics; however, the order of
the standards included in any unit does not imply a sequence of content within that unit. Some standards may be revisited several times
during the course; others may be only partially addressed in different units, depending on the mathematical focus of the unit.
Throughout Algebra II, students should continue to develop proficiency with the Common Core's eight Standards for Mathematical Practice:
1. Make sense of problems and persevere in solving them.
2. Reason abstractly and quantitatively.
3. Construct viable arguments and critique the reasoning of others.
4. Model with mathematics.
5. Use appropriate tools strategically.
6. Attend to precision.
7. Look for and make use of structure.
8. Look for and express regularity in repeated reasoning.
These practices should become the natural way in which students come to understand and to do mathematics. While, depending on the
content to be understood or on the problem to be solved, any practice might be brought to bear, some practices may prove more useful
than others. Opportunities for highlighting certain practices are indicated in different units of study in this sample scope and sequence, but
this highlighting should not be interpreted to mean that other practices should be neglected in those units.
This scope and sequence reflects our current thinking related to the intent of the CCSS for Mathematics, but it is an evolving document. We
expect to make refinements to this scope and sequence in the coming months in response to new learnings about the standards. In
planning your district's instructional program, you should be prepared to have similar flexibility in implementing your district's own scope
and sequence for the next 2 to 3 years, as you transition from your state's current standards to full implementation of the CCSS for
Mathematics.

This topic links the basic functions to which
students were introduced in Algebra I to the new
functions they will master in Algebra II. This topic
builds on previous work with linear and quadratic
functions to help students make sense of the
behavior they see in the larger family of
polynomial functions.The topic leads students to
understand that polynomials form a system
analogous to the integers, namely, they are
closed under the operations of addition,

Students learn how polynomials model some
behaviors with varying rates of change, and they
see how the degree of the polynomial relates to
the number of real zeros and the number of local
extreme values of the polynomial function.
Students then apply this knowledge to choose
appropriate models for situations based on how
quantities in the situation vary, with particular
emphasis on short term and end behavior.
Students will also interpret parts of an
expression, such as terms, factors, and
coefficients as well as interpret complicated
expressions by viewing one or more of their
parts as a single entity.

In this topic, students define three
trigonometric functions: y = sin α, y = cos α and y
= tan α based on the unit circle.
Students learn to use transformations to model
periodic situations. They also develop the
Pythagorean identity from the unit circle and
derive related identities.
In this topic, students draw upon their
knowledge of different parent functions,
including linear, polynomial, power, exponential,
logarithmic and trigonometric functions, to
choose the appropriate model for a given
situation. Students write and solve equations,
inequalities, and systems of equations and
inequalities to answer questions that arise from
these situations.

Drawing correct conclusions from data is highly
dependent on how the data are collected. In

only arise from properly conducted experiments,

randomization is used in each case.
