Unit Overview Unit 1: Quantitative Relationships, Graphs, and Functions Essential Questions Ø In what ways can we manipulate an algebraic equation to find the value of an unknown quantity? Ø How do variables help you model real-­‐world situations and solve equations? Ø How can you determine if something is a mathematical function? Ø How can we use mathematical models to describe physical relationships? Ø How can we use different tools and representations to solve problems? Ø How can the same linear relationship be represented in multiple ways? Enduring Understandings Ø By applying mathematical properties, a linear equation can be manipulated to produce many different but equivalent forms. These manipulations can lead to solution for the unknown value. Ø Units can be used to describe and explain steps and solutions of problems that model a real world scenario. Ø Functions can be categorized into function families, each with their own algebraic and graphical characteristics. Ø There are often two quantities that change in problem situations. One of these quantities depends on the other, making it the dependent quantity and the other the independent quantity Ø A mathematical function is a relation between a set of inputs (values of the domain) and outputs (values of the range) in which one element of the domain is assigned to exactly one element of the range. Ø A linear relationship is one where the dependent quantity is changing at a constant rate per unit of the independent quantity. Ø A Linear function can be represented in multiple ways and can be used to model and solve problems in a real world context. Common Core State Standards 1) A.REI.1: Explain each step in solving a simple equation as following from the equality of numbers asserted at the previous step, starting from the assumption that the original equation has a solution. Construct a viable argument to justify a solution method. 2) A.REI.3: Solve linear equations and inequalities in one variable, including equations with coefficients represented by letters. 3) F.IF.1: Understand that a function from one set (called the domain) to another set (called the range) assigns to each element of the domain exactly one element of the range. If f is a function and x is an element of its domain, then f(x) denotes the output of f corresponding to the input x. The graph of f is the graph of the equation y = f(x). 4) N.Q.1: Use units as a way to understand problems and to guide the solution of multi-­‐step problems; choose and interpret units consistently in formulas; choose and interpret the scale and the origin in graphs and data displays. 5) N.Q.2: Define appropriate quantities for the purpose of descriptive modeling. 6) N.Q.3: Choose a level of accuracy appropriate to limitations on measurement when reporting quantities. 7) A.REI.10: Understand that the graph of an equation in two variables is the set of all its solutions plotted in the coordinate plane, often forming a curve (which could be a line). 8) A.CED.1: Create equations and inequalities in one variable and use them to solve problems. Include equations arising from linear and quadratic functions, and simple rational and exponential functions. 9) A.CED.2: Create equations in two or more variables to represent relationships between quantities; graph equations on coordinate axes with labels and scales. 10) F.IF.2: Use function notation, evaluate functions for inputs in their domains, and interpret 2

statements that use function notation in terms of a context. 11) F.IF.5: Relate the domain of a function to its graph and, where applicable, to the quantitative relationship it describes. For example, if the function h(n) gives the number of person-­‐hours it takes to assemble n engines in a factory, then the positive integers would be an appropriate domain for the function.* 12) F.IF.7a: Graph functions expressed symbolically and show key features of the graph, by hand in simple cases and using technology for more complicated cases.* Graph linear and quadratic functions and show intercepts, maxima, and minima. 13) F.LE.1b: Recognize situations in which one quantity changes at a constant rate per unit interval relative to another. 14) A.SSE.1: Interpret expressions that represent a quantity in terms of its context.

Lesson 2: Using models for integer operation (multiplication/division) Objectives • By examining patterns in tables, students will be able to construct rules for multiplying signed numbers and multiply/divide integers fluently by correctly completing ___ out of ____ parts on a “cheat sheet.” Focused Mathematical Practices • MP 2: Reason abstractly and quantitatively • MP 5: Use appropriate tools strategically (use the model provided) • MP 8: Look for and express regularity in repeated reasoning Vocabulary • Product Common Misconceptions • Students may be able to complete tables and observe patterns, yet still struggle with constructing rules for products of signed numbers. Consider providing additional supports such as asking them to create their own table with new numbers, giving them sets of 4 multiplication problems (one of each kind) where they have to use the tables to find the answer, or pairing them with varied levels. Lesson Clarifications • Only focus on the Opener and Consolidation Activity • May need to supplement with additional examples/tables CCSS Concepts What students will know 7.NS.2: Apply and Review extend previous • Knowing the resulting understandings of sign of any product multiplication and New division and of fractions • Using patterns in tables to multiply and divide to explain the product rational numbers. of signed integers • Constructing rules for multiplying signed numbers Skills What students will be able to do Review • Multiplying integers New • Material/ Resource AM 2.4 Suggested Pacing 1 day Assessment Check Point AR 2.1 8

Lesson 3: Variables and expressions Objectives • Given pictorial and abstract representations of variable expressions, students will create, simplify, justify the equivalency of expressions with ___ out of ___ answered correctly on an exit ticket. Focused Mathematical Practices • MP 2: Reason abstractly and quantitatively (use numerical examples to reason how combining like terms works with variables) • MP 3: Construct viable arguments and critique the reasoning of others • MP 6: Attend to precision (use correct vocabulary and require students to do the same) • MP 7: Look for and make use of structure Vocabulary • Variable, combining like terms, algebraic expression, algebraic equation, term, evaluate, term Common Misconceptions • Students will often think that 3x + 2 is equivalent to 5x. Anticipate this misconception and have students experiment with the validity of this statement by evaluating the two expressions using the same values as x, and comparing results. Also incorporate exercises where students have to critique work done by “other students” and provide reasoning as to whether or not it is correct (MP 2 and MP 3). • Students may struggle with treating an expression such as x + 7 as a single entity. Have students use parentheses as needed. For example, if a problem asks a student to represent “take a number, add 5 to it, then multiply that by 2” as an algebraic expression, students may struggle with preserving the “n+5” as the first operation, and not see that they have to put that in parentheses before multiplying it by 2. Also, get students in the habit of evaluating expressions (when applicable) as a way to test if they think their expression is correct or not. • Students often think that when they see an “x” by itself, that it equals 1. It does NOT EQUAL 1, because x can represent ANY VALUE; however it can be stated that x is being MULTIPLIED by 1. Lesson Clarifications • This lesson should only focus on expressions with variable at a time (there may be 2 variables for exercises in AM 3.3). Problems should stay relatively simple; see the AR 3.1 to determine the level of rigor that is expected. • Suggested outline: o AM 3.1: #’s 2 and 3 in the Core Activity (slides 4-­‐8). This introduces expressions and variables, and allows students create expressions from written “directions.” o AM 3.3: #’s 1 and 2 in the Opener. This allows students to evaluate variable expressions based on given values. This part will need to be supplemented with additional examples using actual variables and some follow up problems as a check for understanding. o AM 3.4: #’s 1-­‐6 in the Core Activity. This allows students to create expressions in a context, simplify them by collecting/combining like terms, and justify the equivalency of the expressions by testing numerical values. The majority of class time should be spent on this section. • This lesson should also be supplemented with an exercise that asks the students to critique someone else’s and construct an argument for whether two expressions are equivalent or not (i.e. 3x + 2 and 5x, 6 + x and 7, 4(x – 1) and 4x – 1).

Lesson 4: Distributive Property Objectives • Through the use of concrete examples and the area model, students will be able to write equivalent expressions using the distributive property by correctly answering ___ out of ____ on an exit ticket. Focused Mathematical Practices • MP 2: Reason abstractly and quantitatively (use numerical examples to reason how the distributive property works with variables) • MP 5: Use appropriate tools strategically (use the model provided) • MP 7: Look for and make use of structure Vocabulary • Distributive property Common Misconceptions • Students often think that 2(x – 7) is equivalent to 2x – 7. Anticipate this misconception and use it as a lesson launch; refer back to it periodically throughout the lesson. • Students struggle with expressions involving subtraction or negative terms. Use the previous lesson and have them rewrite all subtraction expressions as equivalent addition expressions. Also, be sure that students recognize that 2x + -­‐7 is the same thing as 2x – 7.

Lesson 5: Input-­‐output tables & intro to functions Objectives • After given a provided strategy and visual representation of an input-­‐output table, students will be able to find the rule for a given set of inputs and outputs, with at least ___ out of ___ answered correctly on an exit ticket. • Through an investigation of input-­‐output relationships, students will be able to provide an informal definition of a function and identify when a “rule” cannot be created for a given set of inputs and outputs, with at least ___ out of ___ answered correctly on an exit ticket. Focused Mathematical Practices • MP 2: Reason abstractly and quantitatively (when explaining why a certain input-­‐output table cannot have a rule) • MP 6: Attend to precision (use correct vocabulary and require students to do the same) • MP 8: Look for and express regularity in repeated reasoning Vocabulary • Inputs, outputs, function Common Misconceptions • Some students may struggle with just coming up with a rule. Resort to the strategy provided, and in the case of linear examples, have them look for patterns in an output column (this only works when the inputs go up by a consecutive amount). For these students, focus on input-­‐output tables that result in a linear rule. • Students will often see different inputs result in the same output and think it is not a function. Use a numerical example with a rule where this might happen to help explain this (i.e. x2). You can also use a vending machine and remote control as examples. In the case of a remote control, no button will result in two channels or functions, that’s impossible! However, a “last channel” button and “5” could both bring you to the same channel or station. Lesson Clarifications • Suggested outline o AM 3.5 #’s 1 and 2 in the Opener o AM 3.5: #’s 1, 2, 4, 5, 6 in the Core Activity o AM 3.5: # 5 in the Consolidation Activity o AM 6.1: #’s 1-­‐3 in the Opener o AM 6.1: #’s 1-­‐2 in the Core Activity (here students should be applying the mathematical definition of a function to the vending machine example) • Input/output tables can be strategically selected or modified in order to prevent too much time spent on coming up with a rule.

F.IF.1: Understand that a function from one set (called the domain) to another set (called the range) assigns to each element of the domain exactly one element of the range. If f is a function and x is an element of its domain, then f(x) denotes the output of f corresponding to the input x. The graph of f is the graph of the equation y = f(x). and outputs should work for each input-­‐
output pair. This rule can also be used to find additional input-­‐output pairs. New Review • A set of inputs and outputs may or may not represent a mathematical function.

Lesson 6: Mathematical functions Objectives • After discussion of a vending machine example, students will be able to explain why something is a function or not, with at least ___ out of ___ answered correctly on an exit ticket. • Given a set of relations in multiple forms (table and graph), students will be able to describe how you can determine if something is a function specifically by looking at a table or a graph, with at least ___ out of ___ answered correctly on an exit ticket. Focused Mathematical Practices • MP 2: Reason abstractly and quantitatively (when explaining why something is a function or not AND when describing how to determine if something is a function from a table and graph) • MP 6: Attend to precision (use correct vocabulary and require students to do the same) Vocabulary • Inputs, outputs, function Common Misconceptions • Students will often see different inputs result in the same output and think it is not a function. Use a numerical example with a rule where this might happen to help explain this (i.e. x2). You can also use a vending machine and remote control as examples. In the case of a remote control, no button will result in two channels or functions, that’s impossible! However, a “last channel” button and “5” could both bring you to the same channel or station. • Some students may think that something is or is not a function for reasons unrelated to the definition of a function. For example, a student may think that there needs to be an obvious pattern/relationship to be a function (i.e. linear) or that it must form a straight line to be a function. Validate that their thinking is intuitively meaningful, but refer these students to the definition of a function, or provide them with an example that IS a function but does not align their reasoning. Lesson Clarifications • If time is an issue, only focus on the Core Activity of AM 6.1 (vending machine example). Strive to complete all of AM 6.2. CCSS Concepts What students will know F.IF.1: Understand that a function from one set (called the domain) to another set (called the range) assigns to each element of the domain exactly one element of the range. If f is a function and x is an element of its domain, then f(x) denotes the output of f corresponding to the input x. The graph of f is the graph of the equation y = f(x).

Lesson 7: Independent vs. dependent quantities Objectives • Given a set of problem situation descriptions, students will be able to identify the independent and dependent quantities and units, and label them correctly on a coordinate plane with at least ____ out of ____ parts answered correctly on an exit ticket. • Given a set of problem situation descriptions, students will be able to recognize how to represent something that is changing at a constant rate with at least ____ out of ____ parts answered correctly on an exit ticket. Focused Mathematical Practices • MP 1: Make sense of problem and persevere in solving them • MP 4: Model with mathematics • MP 6: Attend to precision (use correct vocabulary and require students to do the same) Vocabulary • Independent quantity/variable, dependent quantity/variable, constant rate of change Common Misconceptions • Some students may struggle with working through a problem situation. Provide students with structure for persevering (i.e. step #1 is to find the variable or changing quantities, step #2 is to determine which is dependent and independent). • Some students may identify key information (i.e. “increases at a rate of 10 gallons per minute) as a variable quantity. Preemptively explain the difference between something that is constant and a quantity that is unknown/changing in a problem situation. • For students who struggle with correctly identifying the independent/dependent quantities, try using one of these questions as a strategy. o “Which quantity depends on the other? Does ____ depend on ____?” o “Which quantify would you input/choose in order to determine the outcome of the other?” Lesson Clarifications CCSS Concepts What students will know N.Q.1: Use units as a way to understand problems and to guide the solution of multi-­‐
step problems; choose and interpret units consistently in formulas; choose and interpret the scale and the origin in graphs and data displays. N.Q.2: Define appropriate quantities for the purpose of descriptive modeling. Review • There are often two quantities (each with their own units) that change in problem situations.

Lesson 8: Domain/ range and discrete/continuous graphs Objectives • Given a set of continuous and discrete graphs and problem situations, students will be able to determine the domain of a function (with and without a context) by answering at least ___ out of ___ questions correctly on an exit ticket. Focused Mathematical Practices • MP 3: Construct viable arguments and critique the reasoning of others (when determining the domain from a problem situation) • MP 6: Attend to precision (use correct vocabulary and require students to do the same) Vocabulary • Relation, Vertical Line Test, continuous graph, discrete graph, function, domain, range Common Misconceptions • If students struggle with understanding the concept of “domain”, try referring to it (in the beginning) as “allowable inputs”. • For students who struggle with choosing a domain, provide contexts that are simple and ask them to think about which values would make sense. (i.e. “Does -­‐5 make sense as an input when talking about the number of miles driven? Does 12.5 make sense when talking about how many t-­‐shirts can be ordered?”) Lesson Clarifications • This lesson is significantly modified from how it was intended to be used in the Carnegie Learning Curriculum. Please refer to the Sample Lesson Plan in this Unit Plan for further information. CCSS F.IF.1: Understand that a function from one set (called the domain) to another set (called the range) assigns to each element of the domain exactly one element of the range.

Lesson 9: Function notation and recognizing function families Objectives • After a mini-­‐lesson introducing function notation, students will be able to write functions using the correct notation given the input and output quantities with at least ___ out of ___ parts answered correctly on an exit ticket • Using technology and a set of functions given symbolically, students will be able to identify sketches of graphs for 4 different function families with at least ___ out of ___ parts answered correctly on an exit ticket Focused Mathematical Practices • MP 5: Use appropriate tools strategically (use graphing calculator to “sketch” functions) • MP 6: Attend to precision (use correct vocabulary and require students to do the same) • MP 8: Look for and express regularity in repeated reasoning (when identifying/generalizing characteristics of function families) Vocabulary • Function notation, linear function, quadratic function, exponential function, absolute value function, increasing/decreasing/constant function, function family, absolute minimum/maximum Common Misconceptions • Some students make mistakes with writing the correct input variable in function notation. Preemptively address this mistake in a quick exercise asking them to find the mistake and correct it (i.e. “What is wrong with f(x) = -­‐4d + 10”) • Some students don’t understand right away that “f(x)” is the output value. Preemptively address this misconception by explaining it is like your “y” and that it is “f of x” and NOT “f times x.” Lesson Clarifications • Do NOT include Problem 4 on page 42 in this lesson (piecewise functions will not be taught in this unit). Also, students can explore linear absolute value functions. However, emphasize that the focus of this year will be on linear, quadratic, and exponential functions. • You will need to provide additional problems/checks for understanding after Problem 1 on page 36 so students can practice writing a function in correct function notation.

Learning Do Now: activities/strategies • Students will cut out all of the graphs on pages 19-­‐25 • Students will pick out the ones that do NOT represent functions. • Students will write an explanation for how they chose these graphs. • Teacher scans room to see if students can correctly identify non-­‐functions AND if their explanation is reasonable and uses vocabulary and the definition of a function (an explanation of “because they fail the Vertical Line Test” is not acceptable) Starter/Launch: • In this lesson, the Do Now can also serve as the launch. It reviews material from the previous lesson but also introduces today’s lesson. Mini lesson: • Teacher directs students to page 32 and introduces the definition of a relation, domain, and range. • Teacher asks students do a word sorting activity (slide 4) • Teacher introduces/reinforces the Vertical Line Test (this may have been introduced in the prior lesson). • Teacher has student volunteers explain how the Vertical Line Test can be applied to graphs of functions AND how it relates to the definition of a function (for example, “You can use the Vertical Line Test by seeing if a vertical line will intersect the graph in more than one point. If this is the case, then that means for the same input, or x-­‐value, there are multiple outputs, or y-­‐values”) • Depending on results from Do Now, teacher quickly draws 3-­‐4 graphs on the SMART board and asks students to write whether or not it is a function (include discrete graphs as well). • Teacher directs students to #1 on page 28 and students work on it independently • Teacher introduces continuous and discrete graphs. • Teacher makes connections between the domain of a function, and how it looks graphically. • Students work in pairs to complete #3 on page 33. Teacher does individual check and reviews answers if necessary. • Teacher explains that domain can be determined from a problem situation as well. Teacher also explains that a domain can sometimes be more specific than just “all integers” based on the problem situation it is modeling. Sometimes, a graph may be represented as continuous data out of convenience (or vice versa) when really it should be discrete. • Teacher directs students to #3 on page 5. Students work in pairs to determine the domain for Something’s Fishy and Music Club. Students also fix (if necessary) the graph of the situation to reflect the correct domain. 38

Teacher uses 2 preselected students to go over answers. •
Class activities: • In this lesson, the class activity is embedded within the mini lesson. See highlighted sections above. Independent Practice: • Students work on CL SA 1.1 and 1.2. • Students first work on page 7, identify each graph (A-­‐H) as continuous or discrete and then write the domain for each. Teacher checks and corrects mistakes seen on A (domain is all real numbers greater than or equal to 1). • Students then work on page 1, #’s 2 and 5. They only need to identify the independent and dependent quantities, then describe the domain for each. Closure: • Teacher presents a scenario on the SMART board about a taxi fare that charges \$1.00 per mile and a \$2.50 flat fee. • Students write down what they think the domain is and WHY they chose this. • Students do a turn and talk, and teacher calls on students to share opinions. Teacher facilitates the conversation so that there is a debate between whether or not to include 0, and whether it should be integers or real numbers. • Teacher explains that sometimes it may be hard to tell, but that it makes it clearer when the domain you choose is justified with your reasoning. • Teacher calls on student volunteers to recap todays lesson by answering some of the following questions: o What word(s) have we learned are related to domain? Range? o What axis represents the domain? Range? o If the domain of a graph is a set of integers, what kind of graph do we call this? o What is the domain of a continuous graph (that extends out both ways forever)?
