MATHEMATICS
Grade 7: Unit 4
Problem Solving with Geometry
2 | P a g e
Course Philosophy/Description In mathematics, students will learn to address a range of tasks focusing on the application of concepts, skills and understandings. Students will be
asked to solve problems involving the key knowledge and skills for their grade level as identified by the NJSLS; express mathematical reasoning and
construct a mathematical argument and apply concepts to solve model real world problems. The balanced math instructional model will be used as
the basis for all mathematics instruction.
Seventh grade Mathematics consists of the following domains: Ratios and Proportional Relationships (RP), The Number System (NS), Expressions
and Equations (EE), Geometry (G), and Statistics and Probability (SP). In seventh grade, instructional time should focus on four critical areas: (1)
developing understanding of and applying proportional relationships; (2) developing understanding of operations with rational numbers and working
with expressions and linear equations; (3) solving problems involving scale drawings and informal geometric constructions, and working with two-
and three-dimensional shapes to solve problems involving area, surface area, and volume; and (4) drawing inferences about populations based on
samples.
1) Students extend their understanding of ratios and develop understanding of proportionality to solve single- and multi-step problems. Students
use their understanding of ratios and proportionality to solve a wide variety of percent problems, including those involving discounts, interest,
taxes, tips, and percent increase or decrease. Students solve problems about scale drawings by relating corresponding lengths between the
objects or by using the fact that relationships of lengths within an object are preserved in similar objects. Students graph proportional
relationships and understand the unit rate informally as a measure of the steepness of the related line, called the slope. They distinguish
proportional relationships from other relationships.
2) Students develop a unified understanding of number, recognizing fractions, decimals (that have a finite or a repeating decimal representation),
and percents as different representations of rational numbers. Students extend addition, subtraction, multiplication, and division to all rational
numbers, maintaining the properties of operations and the relationships between addition and subtraction, and multiplication and division. By
applying these properties, and by viewing negative numbers in terms of everyday contexts (e.g., amounts owed or temperatures below zero),
students explain and interpret the rules for adding, subtracting, multiplying, and dividing with negative numbers. They use the arithmetic of
rational numbers as they formulate expressions and equations in one variable and use these equations to solve problems.
3) Students continue their work with area from Grade 6, solving problems involving the area and circumference of a circle and surface area of
three-dimensional objects. In preparation for work on congruence and similarity in Grade 8 they reason about relationships among two-
dimensional figures using scale drawings and informal geometric constructions, and they gain familiarity with the relationships between
angles formed by intersecting lines. Students work with three-dimensional figures, relating them to two-dimensional figures by examining
cross-sections. They solve real-world and mathematical problems involving area, surface area, and volume of two- and three-dimensional
objects composed of triangles, quadrilaterals, polygons, cubes and right prisms.
4) Students build on their previous work with single data distributions to compare two data distributions and address questions about differences
between populations. They begin informal work with random sampling to generate data sets and learn about the importance of representative
samples for drawing inferences.

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 Sudent 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 New Jersey Student Learning Standards (NJSLS). 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 home language
(L1) 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
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
6 | P a g e
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 reteaches as necessary. (whole
group instruction, small group instruction, or centers)
Teacher and students practice mathematics
processes together through interactive
activities, problem solving, and discussion.
(whole group or small group instruction)

interactive sites for appropriate instructional videos and/or information pertaining to strategies and modeling for describing 2-dimensional figure that
results when a 3-dimensional figure is sliced from multiple angles.
Design
Develop a proposal for a chosen solution that include models (physical, graphical or mathematical) to communicate the solution to peers.
Example: Teachers can use geometry software to draw and construct triangles with given conditions. https://www.geogebra.org/m/JHgTXKrt
Computational Thinking: Programming:
Develop an algorithm to solve an assigned problem using a specified set of commands and use peer review to critique the solution.
Example: Student can use conceptual investigations to create algorithms for finding the area, volume or surface area two and three-dimensional
objects.

Career Ready Practices
Career Ready Practices describe the career-ready skills that all educators in all content areas should seek to develop in their students. They are
practices that have been linked to increase college, career, and life success. Career Ready Practices should be taught and reinforced in all career
exploration and preparation programs with increasingly higher levels of complexity and expectation as a student advances through a program of
study.
CRP2. Apply appropriate academic and technical skills.
Career-ready individuals readily access and use the knowledge and skills acquired through experience and education to be more productive. They make
connections between abstract concepts with real-world applications, and they make correct insights about when it is appropriate to apply the use of an
academic skill in a workplace situation.
Example: Students will apply prior knowledge when solving real world problems. Students will make sound judgements about the use of specific
tools, such as rulers and protractors to draw geometric shapes with given conditions.
CRP4. Communicate clearly and effectively and with reason.
Career-ready individuals communicate thoughts, ideas, and action plans with clarity, whether using written, verbal, and/or visual methods. They
communicate in the workplace with clarity and purpose to make maximum use of their own and others’ time. They are excellent writers; they master
conventions, word choice, and organization, and use effective tone and presentation skills to articulate ideas. They are skilled at interacting with others;
they are active listeners and speak clearly and with purpose. Career-ready individuals think about the audience for their communication and prepare
accordingly to ensure the desired outcome.
Example: Students will on a daily basis communicate their reasoning behind their solution paths by making connections to the context and the
quantities, using proper vocabulary, along with decontextualizing and/or contextualizing the problem. Students will create simulations for finding
surface area and volume of cubes, triangular and rectangular prisms. They will also explain the meaning behind the quantities and units involved.
Students will also ask probing questions to clarify and improve arguments.
CRP8. Utilize critical thinking to make sense of problems and persevere in solving them.
Career-ready individuals readily recognize problems in the workplace, understand the nature of the problem and devise effective plans to solve the
problem. They are aware of problems when they occur and take action quickly to address the problem; they thoughtfully investigate the root cause of
the problem prior to introducing solutions. They carefully consider the options to solve the problem. Once a solution is agreed upon, they follow
through to ensure the problem is solved, whether through their own actions or the actions of others.
10 | P a g e
Career Ready Practices
Example: Throughout their daily lessons, students will understand the meaning of a problem and look for entry points into solving their problems by
analyzing the relationships of the quantities, constraints and goals of the task. Plans for solution paths will be made and have meaning. Students will
self-monitor, evaluate and critique their process and progress as they are working and make changes as necessary.
CRP12. Work productively in teams while using cultural global competence.
Career-ready individuals positively contribute to every team, whether formal or informal. They apply an awareness of cultural difference to avoid
barriers to productive and positive interaction. They find ways to increase the engagement and contribution of all team members. They plan and
facilitate effective team meetings.
Example: Students will work in collaborative and whole group settings to develop various solutions to math tasks that are presented to them. They
will work together to understand the terms of the problem, ask clarifying and challenging questions among each other, and develop agreed upon solutions
using a variety of strategies and models. Students will listen to, read and discuss arguments with each other with respect and courtesy at all times and
will be willing to assist those that may need assistance. In this unit students will demonstrate and explain to a peer or small group how to solve multi-
step ratio and percent problems using proportional relationships.

Culturally Relevant Pedagogy Examples
Problem-Based Learning Scenarios: Present relatable real-world problems for your students to solve, explicitly
referencing cultures and communities when applicable.
Example: Students look up menus from their favorite restaurant and choose a meal for each member of their family. Have them
determine total cost, inclusive of tax of 7% and gratuity of 15%, 18% and 20%.
Integrate Relevant Word Problems: Contextualize equations using word problems that reference student interests and
cultures.
Example: Create and use word problems that students relate to, have prior knowledge of and includes their interest. These can
include current events and/or relevant real-world situations. Using content that students can relate to adds meaning, value and
connection. The following link provides you with a variety of word problems that are current, relevant to real-world and student
interests: https://www.yummymath.com/
Everyone has a Voice: Create a classroom environment where students know that their contributions are expected and
valued.
Example: Establish norms for sharing that promote discourse and 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 to increase students’ retention. Use multi-modal activities, analogies, realia,
visual cues, graphic representations, gestures, pictures, practice and cognates. Inform students that some vocabulary words have
multiple meanings. Have students create the Word Wall with their definitions and examples to foster ownership. Work with students
to create a sorting and matching game using vocabulary words from within the unit. Students can work in teams or individually to
play these games. This will allow students to familiarize themselves with the vocabulary words within the unit.

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
