Course Philosophy/Description
Algebra I Honors is a rigorous course designed to develop and extend the algebraic concepts and processes that can be used to solve a variety of real-
world and mathematical problems. The fundamental purpose of Algebra 1 is to formalize and extend the mathematics that students learned in the
elementary and middle grades. The Standards for Mathematical Practice apply throughout each course, and, together with the New Jersey Student
Learning Standards, prescribe that students experience mathematics as a coherent, useful, and logical subject that makes use of their ability to make
sense of problem situations. Conceptual knowledge behind the mathematics is emphasized. Algebra I provides a formal development of the algebraic
skills and concepts necessary for students to succeed in advanced courses as well as the PARCC. The course also provides opportunities for the
students to enhance the skills needed to become college and career ready. Students will learn and engage in applying the concepts through the use of
high-level tasks and extended projects. This course is designed for students who are highly motivated in the areas of Math and/or Science.
The content shall include, but not be limited to, perform set operations, use fundamental concepts of logic including Venn diagrams, describe the
concept of a function, use function notation, solve real-world problems involving relations and functions, determine the domain and range of
relations and functions, simplify algebraic expressions, solve linear and literal equations, solve and graph simple and compound inequalities, solve
linear equations and inequalities in real-world situations, rewrite equations of a line into slope-intercept form and standard form, graph a line given
any variation of information, determine the slope, x- and y- intercepts of a line given its graph, its equation or two points on the line, write an
equation of a line given any variation of information, determine a line of best fit and recognize the slope as the rate of change, factor polynomial
expressions, perform operations with polynomials, simplify and solve algebraic ratios and proportions, simplify and perform operations with radical
and rational expressions, simplify complex fractions, solve rational equations including situations involving mixture, distance, work and interest,
solve and graph absolute value equations and inequalities, graph systems of linear equations and inequalities in two and three variables and quadratic
functions, use varied solution strategies for quadratic equations and for systems of linear equations and inequalities in two and three variables,
perform operations on matrices, and use matrices to solve problems.
in two and three variables.

ESL Framework
This ESL framework was designed to be used by bilingual, dual language, ESL and general education teachers. Bilingual and dual language programs
use the home language and a second language for instruction. ESL teachers and general education or bilingual teachers may use this document to
collaborate on unit and lesson planning to decide who will address certain components of the SLO and language objective. ESL teachers may use the
appropriate leveled language objective to build lessons for ELLs which reflects what is covered in the general education program. In this way, whether
it is a pull-out or push-in model, all teachers are working on the same Student Learning Objective connected to the New Jersey Student Learning
Standards. The design of language objectives are based on the alignment of the World-Class Instructional Design Assessment (WIDA) Consortium’s
English Language Development (ELD) standards with the Common Core State Standards (CCSS). WIDA’s ELD standards advance academic language
development across content areas ultimately leading to academic achievement for English learners. As English learners are progressing through the six
developmental linguistic stages, this framework will assist all teachers who work with English learners to appropriately identify the language needed
to meet the requirements of the content standard. At the same time, the language objectives recognize the cognitive demand required to complete
educational tasks. Even though listening and reading (receptive) skills differ from speaking and writing (expressive) skills across proficiency levels the
cognitive function should not be diminished. For example, an Entering Level One student only has the linguistic ability to respond in single words in
English with significant support from their home language. However, they could complete a Venn diagram with single words which demonstrates that
they understand how the elements compare and contrast with each other or they could respond with the support of their native language with assistance
from a teacher, para-professional, peer or a technology program.

Research about Teaching and Learning Mathematics Structure teaching of mathematical concepts and skills around problems to be solved (Checkly, 1997; Wood & Sellars, 1996; Wood & Sellars, 1997)
Encourage students to work cooperatively with others (Johnson & Johnson, 1975; Davidson, 1990)
Use group problem-solving to stimulate students to apply their mathematical thinking skills (Artzt & Armour-Thomas, 1992)
Students interact in ways that support and challenge one another’s strategic thinking (Artzt, Armour-Thomas, & Curcio, 2008)
Activities structured in ways allowing students to explore, explain, extend, and evaluate their progress (National Research Council, 1999)
There are three critical components to effective mathematics instruction (Shellard & Moyer, 2002):
• Teaching for conceptual understanding within the Balanced Math approach
• Developing children’s procedural literacy
• Promoting strategic competence through meaningful problem-solving investigations
Teachers should be:
• Demonstrating acceptance and recognition of students’ divergent ideas.
• Challenging students to think deeply about the problems they are solving, extending thinking beyond the solutions and algorithms required
to solve the problem
• Influencing learning by asking challenging and interesting questions to accelerate students’ innate inquisitiveness and foster them to
examine concepts further.
• Projecting a positive attitude about mathematics and about students’ ability to “do” mathematics
Students should be:
• Actively engaging in “doing” mathematics
• Solving challenging problems
• Investigating meaningful real-world problems
• Making interdisciplinary connections
• Developing an understanding of mathematical knowledge required to “do” mathematics and connect the language of mathematical ideas
with numerical representations
• Sharing mathematical ideas, discussing mathematics with one another, refining and critiquing each other’s ideas and understandings
• Communicating in pairs, small group, or whole group presentations
• Using multiple representations to communicate mathematical ideas
• Using connections between pictures, oral language, written symbols, manipulative models, and real-world situations
• Using technological resources and other 21st century skills to support and enhance mathematical understanding
7 | P a g e B o a r d A p p r o v e d 0 9 . 0 8 . 2 0 2 1
Mathematics is not a stagnate field of textbook problems; rather, it is a dynamic way of constructing meaning about the world around us,
generating knowledge and understanding about the real world every day. Students should be metaphorically rolling up their sleeves and “doing
mathematics” themselves, not watching others do mathematics for them or in front of them. (Protheroe, 2007)
Balanced Mathematics Instructional Model
Balanced math consists of three different learning opportunities; guided math, shared math, and independent math. Ensuring a balance of all three
approaches will build conceptual understanding, problem solving, computational fluency, and procedural fluency. Building conceptual
understanding is the focal point of developing mathematical proficiency. Students should frequently work on rigorous tasks, talk about the math,
explain their thinking, justify their answer or process, build models with graphs or charts or manipulatives, and use technology.
When balanced math is used in the classroom it provides students opportunities to:
• solve problems
• make connections between math concepts and real-life situations
• communicate mathematical ideas (orally, visually and in writing)
• choose appropriate materials to solve problems
• reflect and monitor their own understanding of the math concepts
• practice strategies to build procedural and conceptual confidence
Teacher builds conceptual understanding by
modeling through demonstration, explicit
instruction, and think-alouds, as well as guiding
students as they practice math strategies and apply
problem solving strategies. (whole group or small
group instruction)
Students practice math strategies independently to
build procedural and computational fluency. Teacher
assesses learning and re-teaches as necessary. (whole
group instruction, small group instruction, or centers)
Teacher and students practice mathematics
processes together through interactive
activities, problem solving, and discussion.

Computer Science and Design Thinking
Standards
8.1.12.DA.5, 8.1.12.DA.6, 8.1.12.AP.1
➢ Data and Analysis
• Create data visualizations from large data sets to summarize, communicate, and support different interpretations of real-
world phenomena.
Example: Students can use Google Docs and digital tools as a means of discussing and collaboratively solving complex tasks that
focus on concepts related to polynomials. https://www.mathsisfun.com/data/
• Create and refine computational models to better represent the relationships among different elements of data collected
from a phenomenon or process.
Example: Students can use digital tools to graph linear systems of inequalities that model a solution to a real world situation.
Students can then write a position statement to justify their solution, mathematical thinking and modeling with peers.
http://www.mathsisfun.com/data/graphs-index.html.
➢ Algorithms & Programming
• Design algorithms to solve computational problems using a combination of original and existing algorithms.
Example: Students can use and explain the advantages of using graphing calculators, GeoGebra or Desmos to graph systems of
inequalities to solve contextual problems. The discussion should also involve developing ways to improve and develop even better
algorithms. https://www.desmos.com/calculator https://www.geogebra.org/geometry?lang=en-US

Career Readiness, Life Literacies and Key Skills
Career readiness, life literacies, and key skills education provides students with the necessary skills to make informed career and financial decisions, engage as
responsible community members in a digital society, and to successfully meet the challenges and opportunities in an interconnected global economy.
• Credit and Debt Management (9.1.12.CDM.8)
Compare and compute interest and compound interest and develop an amortization table using business tools.
Example: Students will use their growing understanding of exponentials functions to compare interest rates and make informed decisions about the
merits and pitfalls of different types of debt.
• Career Awareness and Planning (9.2.12.CAP.10)
Identify strategies for reducing overall costs of postsecondary education (e.g. tuition assistance, loans, grants, scholarships, and student loans.
Example: Students will compare the immediate and long term costs and benefits of different options available to pay for college and career education
after high school. Students can develop a suggested plan for hypothetical students based on their qualifications and financial circumstances.
• Technology Literacy (9.4.12.TL.1)
Assess digital tools based on features of accessibility options, capacities, and utility for accomplishing a specified task.
Example: Students can use and explain the advantages of using graphing calculators, GeoGebra or Desmos to graph systems of inequalities
to solve contextual problems. The discussion should also involve developing ways to improve and develop even better algorithms.

Culturally Relevant Pedagogy Examples
• Everyone has a Voice: Create a classroom environment where students know that their contributions are expected and
valued.
Example: Norms for sharing are established that communicate a growth mindset for mathematics. All students are capable of
expressing mathematical thinking and contributing to the classroom community. Students learn new ways of looking at problem
solving by working with and listening to each other. • Present New Concepts Using Student Vocabulary: Use student diction to capture attention and build understanding before
using academic terms.
Example: Teach math vocabulary in various modalities for students to remember. Use multi-modal activities, analogies, visual
cues, graphic representations, gestures, pictures, practice and cognates. Model to students that some vocabulary has multiple
meanings. Have students create the Word Wall with their definitions and examples to foster ownership.
• Establish Inclusion: Highlight how the topic may relate or apply to students.
Example: After a brief explanation of slope, have students come up with examples of slope at home, in their neighborhood and
outside of their neighborhood. After having a volunteer list a few in each category, use the examples in class with the students.
Establishing inclusion also involves regularly grouping students with different classmates to share unique perspectives.
• Integrate Relevant Word Problems: Contextualize equations using word problems that reference student interests and
cultures.
Example: When learning different types of functions, problems that relate to student interests such as music, sports and art enable the
students to understand and relate to the concept in a more meaningful way.
• Encourage Student Leadership: Create an avenue for students to propose problem solving strategies and potential projects.
Example: Students can learn about different function types by creating problems together and deciding if the problems fit the
necessary criteria. This experience will allow students to discuss and explore their current level of understanding by applying the
concepts to relevant real-life experiences.

Example practices that address Self-Awareness:
• Clearly state classroom rules
• Provide students with specific feedback regarding
academics and behavior
• Offer different ways to demonstrate understanding
• Create opportunities for students to self-advocate
• Check for student understanding / feelings about
performance
• Check for emotional wellbeing
• Facilitate understanding of student strengths and
challenges
Students scan multistep contextual problems that
require them to identify variables, write
equations, create graphs, etc., and make a list of
questions based on their understanding to ask the
teacher. This well help them to gain confidence
in working through the problems.
Set up small-group discussions that allows
students to reflect and discuss challenges or how
they solved a problem they faced. Students can
discuss their process and challenges when
writing linear and exponential functions given a
graph, table of values, or written description.

Example practices that address Self-
Management:
• Encourage students to take pride/ownership in
work and behavior
• Encourage students to reflect and adapt to
classroom situations
• Assist students with being ready in the classroom
• Assist students with managing their own emotional
states
Lead discussions that encourages students to
reflect on barriers they encounter when
completing an assignment (e.g., finding a
computer, needing extra help or needing a quiet
place to work) and help them think about
solutions to overcome those barriers.
Teach and model for students how to give and
receive feedback on errors/flaws in their
reasoning. As a result of these self-management
efforts, the class is able to engage in productive
and positive discussion on the definition of
functions.

• Plan for project-based learning
• Assist students with discovering individual
strengths
• Model and promote respecting differences
• Model and promote active listening
• Help students develop communication skills
• Demonstrate value for a diversity of opinions
Instead of simply jumping into their own
solution when attempting to model with linear
functions, linear systems and exponential
functions, have student discuss their approach to
the problem in small groups. In doing so, they
demonstrate good relationship skills by listening
and responding to each other.
During class or group discussion, have students
expound upon and clarify each other’s questions
and comments, ask follow-up questions and
clarify their own questions and reasoning.

Decision-Making:
• Support collaborative decision making for
academics and behavior
• Foster student-centered discipline
• Assist students in step-by-step conflict resolution

• Foster student independence
• Model fair and appropriate decision making
• Teach good citizenship
Use a lesson to teach students a simple formula
for making good choices. (e.g., stop, calm down,
identify the choice to be made, consider the
options, make a choice and do it, how did it go?)
Post the decision-making formula in the
classroom.
Routinely encourage students to use the
decision-making formula as they face a choice
(e.g., whether to finish homework or go out with
a friend). Support students through the steps of
making a decision anytime they face a choice or
decision. Simple choices like “Which tool
should I use to explain the relationship between
domain and range?” or “Do I need a calculator
for this problem?” are good places to start.

Enrichment
What is the Purpose of Enrichment?
• The purpose of enrichment is to provide extended learning opportunities and challenges to students who have already mastered, or can quickly master, the
basic curriculum. Enrichment gives the student more time to study concepts with greater depth, breadth, and complexity.
• Enrichment also provides opportunities for students to pursue learning in their own areas of interest and strengths.
• Enrichment keeps advanced students engaged and supports their accelerated academic needs.
• Enrichment provides the most appropriate answer to the question, “What do you do when the student already knows it?”
Enrichment is…
• Planned and purposeful
• Different, or differentiated, work – not just more work
• Responsive to students’ needs and situations
• A promotion of high-level thinking skills and making connections
within content
• The ability to apply different or multiple strategies to the content
• The ability to synthesize concepts and make real world and cross-
curricular connections
• Elevated contextual complexity
• Sometimes independent activities, sometimes direct
instruction
• Inquiry based or open-ended assignments and projects
• Using supplementary materials in addition to the normal range
of resources
• Choices for students
• Tiered/Multi-level activities with flexible groups (may change
daily or weekly)
Enrichment is not…
• Just for gifted students (some gifted students may need
intervention in some areas just as some other students may need
frequent enrichment)
• Worksheets that are more of the same (busywork)
• Random assignments, games, or puzzles not connected to the
content areas or areas of student interest
• Extra homework
• A package that is the same for everyone
• Thinking skills taught in isolation
• Unstructured free time

other produces a system with the same solutions.
A.REI.D.11: Explain why the x-coordinates of the points where the graphs of the equations y = f(x) and y = g(x) intersect are the solutions of the
equation f(x) = g(x); find the solutions approximately, e.g., using technology to graph the functions, make tables of values, or find successive

N.RN.A.1: Explain how the definition of the meaning of rational exponents follows from extending the properties of integer exponents to those
values, allowing for a notation for radicals in terms of rational exponents. For example, we define 51/3 to be the cube root of 5 because we want
(51/3) 3 = 5(1/3) 3 to hold, so (51/3) 3 must equal 5

F.IF.B.4: For a function that models a relationship between two quantities, interpret key features of graphs and tables in terms of the quantities,
and sketch graphs showing key features given a verbal description of the relationship. Key features include: intercepts; intervals where the
function is increasing, decreasing, positive, or negative; relative maximums and minimums; symmetries; end behavior; and periodicity. *[Focus

F.BF.B.3: Identify the effect on the graph of replacing f(x) by f(x) + k, k f(x), f(kx), and f(x + k) for specific values of k (both positive and negative);
find the value of k given the graphs. Experiment with cases and illustrate an explanation of the effects on the graph using technology. Include
recognizing even and odd functions from their graphs and algebraic expressions for them.
F.LE.A.1a: Prove that linear functions grow by equal differences over equal intervals, and that exponential functions grow by equal factors over
equal intervals.
A.SSE.B.3c: Use the properties of exponents to transform expressions for exponential functions. For example the expression 1.15t can be
rewritten as (1.151/12) 12t ≈1.01212t to reveal the approximate equivalent monthly interest rate if the annual rate is 15%.
F.IF.C.8b: Use the properties of exponents to interpret expressions for exponential functions. For example, identify percent rate of change in
functions such as y = (1.02)t , y = (0.97)t , y = (1.01)12t, y = (1.2)t/10, and classify them as representing exponential growth or decay.

N.RN.A.1: Explain how the definition of the meaning of rational exponents follows from extending the properties of integer exponents to those
values, allowing for a notation for radicals in terms of rational exponents. For example, we define 51/3 to be the cube root of 5 because we want
(51/3) 3 = 5(1/3) 3 to hold, so (51/3) 3 must equal 5

Integrated Evidence Statements
F-IF.A.Int.1: Understand the concept of a function and use function notation.
• Tasks require students to use function notation, evaluate functions for inputs in their domains, and interpret statements that use function
notation in terms of a real-world context • About a quarter of tasks involve functions defined recursively on a domain in the integers.
F-Int.1-1: Given a verbal description of a linear or quadratic functional dependence, write an expression for the function and demonstrate various
knowledge and skills articulated in the Functions category in relation to this function.
• Given a verbal description of a functional dependence, the student would be required to write an expression for the function and then, e.g.,
identify a natural domain for the function given the situation; use a graphing tool to graph several input-output pairs; select applicable features
of the function, such as linear, increasing, decreasing, quadratic, nonlinear; and find an input value leading to a given output value. o e.g., a functional dependence might be described as follows: "The area of a square is a function of the length of its diagonal." The
student would be asked to create an expression such as f(x) = (1/2) x 2 for this function. The natural domain for the function would be
the positive real numbers. The function is increasing and nonlinear. And so on. o e.g., a functional dependence might be described as follows: "The slope of the line passing through the points (1, 3) and (7, y) is a
function of y." The student would be asked to create an expression such as s(y) = (3- y)/(1-7) for this function. The natural domain for
this function would be the real numbers. The function is increasing and linear. And so on.
HS-Int.2: Solve multi-step mathematical problems with degree of difficulty appropriate to the course that requires analyzing quadratic functions
and/or writing and solving quadratic equations.
• Tasks do not have a real-world context. • Exact answers may be required or decimal approximations may be given. Students might choose to take advantage of the graphing utility to
find approximate answers or clarify the situation at hand. For rational solutions, exact values are required. For irrational solutions, exact or
decimal approximations may be required. Simplifying or rewriting radicals is not required. Some examples: Given the function f(x) = 𝑥 2 + x, find all values of k such that f(3 - k) = f(3). (Exact answers are required.)

HS.C.12.1: Construct, autonomously, chains of reasoning that will justify or refute propositions or conjectures about functions. Content
scope: F-IF.8a
• Tasks involve using algebra to prove properties of given functions. For example, prove algebraically that the function h(t) = t(t-1) has
minimum value 14 ; prove algebraically that the graph of g(x) = x2 - x + 14 is symmetric about the line x = 12 ; prove that x2+ 1 is never less
than -2x.
• Scaffolding is provided to ensure tasks have appropriate level of difficulty. (For example, the prompt could show the graphs of x2+1 and -2x
on the same set of axes, and say, "From the graph, it looks as if x2+ 1 is never less than -2x. In this task, you will use algebra to prove it." And
so on, perhaps with additional hints or scaffolding.)
