Common Core Standards Plus Mathematics Grade 8 Domain: Functions Focus: Comparing the Properties of Two Functions Lesson: #17 Standard: 8.F.2: Compare properties of two functions each represented in a different way (algebraically, graphically, numerically in tables, or by verbal descriptions). Lesson Objective: Students will compare the properties of two functions. Introduction: Today we will continue to compare the properties of two functions in different forms. We have been comparing functions but we did not cover verbal descriptions. Today we will incorporate verbal descriptions in the comparisons. Instruction: We will read the verbal description and translate the verbal description to an equation. If the equation does not directly transfer to slope-intercept form, then we will re-write the equation into slope-intercept form. We already know how to write equations from graphs and tables and how to re-write standard form equations to slope-intercept form equations. Sample Daily Lesson- Teacher Lesson Plan Guided Practice: Let s complete the example together. A number y is three more than half a number x. What is the translation to an equation? Yes, it s 1 y x 3. To be able to compare it 2 to the standard form equation, let s re-write function 2 to slope-intercept form. We first subtract 3x then multiply by 1. We end up with 3 y x 2. Now we are ready to write a comparison. 5 5 Function 2 has a greater rate of change since 3 1. Function 1 has a greater 5 2 y-intercept/initial value/vertical shift. Independent Practice: Follow the same process we did with the example problem to complete the practice problems. Review: When the students are finished, go over the problems. If the students do not have enough time to finish, then they can write down the answers as you go over the problems. Closure: Today you compared the properties of functions represented in two forms. One of the forms was a verbal description and the other form was written graphically, algebraically as an equation, or numerically in a table form. Answers: 1. Verbal description equation: y 3x 2; Graph equation: 3 y x 3 2 Comparison: The verbal description function has a greater rate of change, since 3, and a greater y-intercept/initial value. The graph has a greater 3 2 vertical shift. 2. Verbal description equation: 1 y x 3 ; Table equation: 1 y x 2 3 2 Comparison: The table equation has a greater rate of change since, 1 1 and a greater y-intercept/initial value., 2 3 The verbal description has a greater vertical shift from the origin. 3. Verbal description equation: y 3x 5; Equation in slope-intercept form: y 2x 5. Comparison: The verbal description has a greater rate of change since 3 > 2. Both functions have the same y-intercept/initial value/vertical shift. 4 www.standardsplus.org - 1.877.505.9152

Common Core Standards Plus Mathematics Grade 8 Domain: Functions Focus: Construct/Interpret a Function to Model a Linear Relationship Lesson: #18 Standard: 8.F.4: Construct a function to model a linear relationship between two quantities. Determine the rate of change and initial value of the function from a description of a relationship or from two (x, y) values, including reading these from a table or from a graph. Interpret the rate of change and initial value of a linear function in terms of the situation it models, and in terms of its graph or a table of values. Lesson Objective: Students will construct and interpret a function to model a linear relationship as well adjust the function given additional information. Introduction: Today you will write a function that models a linear relationship given to you in words and in a table. You will also adjust the function when given new information. Sample Daily Lesson- Teacher Lesson Plan Instruction: We have had practice translating verbal descriptions to linear equations. Today we will be given a situation with two variables. You will need to determine the two variables, how to represent them algebraically, and which variable is the dependent variable, and which is the independent variable. You will then need to determine the rate of change and the initial value. Finally, you will write an equation in slope-intercept form. Once you have determined the equation, you will answer questions related to the function. Guided Practice: Let s complete the example together. An empty egg carton weighs 0.6 ounce. Each egg placed in the carton weighs on average 2.3 ounces. Represent the total weight of the carton, w, with x eggs. Our two variables are defined for us already. Which variable is the dependent variable? Yes, the weight of the carton. So the independent variable is the number of eggs, x. What is the initial value? Yes, it s the weight of the empty carton, which is 0.6 ounces. What is the rate of change? Yes, it s the ounces per egg, which is 2.3 ounces per egg. Since we identified all the parts we need to write an equation in slopeintercept form, we write w 2.3x 0.6. Independent Practice: It s your turn to apply the same process to the practice problems. Review: When the students are finished, go over the problems. Closure: Today you wrote a function that modeled a linear relationship given to you in words and in a table. You also adjusted your function when given new information. Answers: 1. Rate of change: 29 feet/hour; Initial value: -200 feet 2. y 29x 200 3. 0 29x 200; x 6.9hours 4.

Common Core Standards Plus Mathematics Grade 8 Domain: Functions Focus: Construct/Interpret a Function to Model a Linear Relationship Lesson: #19 Standard: 8.F.4: Construct a function to model a linear relationship between two quantities. Determine the rate of change and initial value of the function from a description of a relationship or from two (x, y) values, including reading these from a table or from a graph. Interpret the rate of change and initial value of a linear function in terms of the situation it models, and in terms of its graph or a table of values. Lesson Objective: Students will construct and interpret functions to model linear relationships and compare the properties of the functions. Introduction: Today you will continue to construct and interpret functions to model linear relationships. You will also compare the properties of the functions you construct. Instruction: You will be given a scenario and a graph. From those different representations, you will determine the variables, initial value, and rate of change. You will then write equations in slope-intercept form to model the relationships. Sample Daily Lesson- Teacher Lesson Plan Guided Practice: Let s complete the example problem together. The cost of gym membership includes the sign-up fee of $75 and a monthly fee of $30. The gym will lower its sign-up fee to $25 after the holidays to attract more members. We need to write a function to model this relationship. First we need to define the variables. The dependent variable is the total cost of gym membership. We ll use y. The independent variable is the number of months. We ll use x. What is the initial value for the gym membership before the holidays? Yes, $75. What is the rate of change? Yes, $30 per month. We can write the function in slope-intercept form as y 30x 75. After the holidays the sign-up fee is reduced to $25. How does this change our function equation? Yes, we change the constant only. Our new function is y 30x 25. How does this change affect the graph of the original equation? Only the constant is changed. The constant is the initial value. The graph is shifted down from our original equation. Independent Practice: It s your turn to apply the same process to the practice problems. You must use the information in both the scenario and the graph to be able to answer the problems. Review: When the students are finished, go over the problems. Closure: Today you continued to construct and interpret functions to model linear relationships. You also compared the properties of the functions you constructed. Answers: 1. Plan A - Initial value: $ 84; Rate of change: - 12/mo. 5. 2. y 12x 84 3. Plan B - Initial value: $84; Rate of change: - $21/mo. 4. y 21x 84 6. Plan B will pay back Teresa faster. The slope of the line representing Plan B is steeper than plan A. The steeper the line, the faster the balance due is decreasing. 8 www.standardsplus.org - 1.877.505.9152

We need to write a function to model the relationship between the number of ounces in the glass at any given time if it is topped off at a rate of 0.5 ounce per second. By looking at the picture, we see the capacity of the glass and the amount of water already in the glass. We are given the rate of change and the initial value. The rate of change is 0.5 ounce per second. The initial value is 7 ounces. We can write the function from these two pieces of information. What is the equation? Yes, it s y 0.5x 7, where y is the amount of ounces in the glass and x is time in seconds. At what point will the glass be full? Since our glass is 10 ounces, we set y equal to 10 and solve for x. We get x = 6 seconds. Our point is (6, 10). Independent Practice: It s your turn to apply the same process to the practice problems. You are given two other glasses and information that you will write functions for. You will graph the three functions on the same graph. You will use the functions and graph to answer questions. Review: When the students are finished, go over the problems. Closure: Today you continued to construct and interpret functions to model linear relationships. You used your model to graph and solve problems. Answers: 1. y x 11 4. (Graph on right.) 2. y 2x 16 3. Answers will vary, the justification is most important. If the student predicts that the 24-oz glass will be filled first, he or she could say because it is being filled at a faster rate. If the student says that the 10-oz glass will be filled first, it could be because it s the smallest size glass. The student could have solved all the equations to find the total seconds for each glass to be topped off. 5. The 24-ounce glass filled first. Student should respond why they expected this or not and why. The justification/ reasoning is very important for this activity. 6. The 24-ounce glass filled at a faster rate. By looking at the graph, the line is steeper. By looking at the equations, the coefficient of x is the greatest for the 24-ounce glass. 7. No. The glass filling at a faster rate will not always fill first. It will depend on both the initial amount of liquid in the glass, and the size of the glass. 10 www.standardsplus.org - 1.877.505.9152

As an additional opportunity to reinforce the vocabulary, concepts, and knowledge presented during the week of instruction. Standard: 8.F.2 Compare properties of two functions each represented in a different way (algebraically, graphically, numerically in tables, or by verbal descriptions). For example, given a linear function represented by a table of values and a linear function represented by an algebraic expression, determine which function has the greater rate of change. 8.F.4 Construct a function to model a linear relationship between two quantities. Determine the rate of change and initial value of the function from a description of a relationship or from two (x, y) values, including reading these from a table or from a graph. Interpret the rate of change and initial value of a linear function in terms of the situation it models, and in terms of its graph or a table of values. Procedure: Read the directions aloud and ensure that students understand how to respond to each item. If you are using the weekly evaluation as a formative assessment, have the students complete the evaluation independently. If you are using it to reinforce the week s instruction, determine the items that will be completed as guided practice, and those that will be completed as independent practice.

Common Core Standards Plus Mathematics Grade 8 Domain: Functions Focus: Sketch a Function Graph Lesson: #21 Standard: 8.F.5: Describe qualitatively the functional relationship between two quantities by analyzing a graph (e.g., where the function is increasing or decreasing, linear or nonlinear). Sketch a graph that exhibits the qualitative features of a function that has been described verbally. Lesson Objective: Students will sketch a function graph given a scenario and describe qualitatively the relationship between quantities of a given graph. Introduction: This week we will conclude our explorations of functions. We will sketch graphs from a verbal description or from a model. We will also describe the relationship between two quantities given a graph. Instruction: To sketch a graph from a scenario, we must identify the variables. We must understand if the relationship between the variables is increasing or decreasing and determine if the relationship is linear or non-linear or a combination of the two. If it is linear, we need to see if there is a change in the rate for the same relationship between the variables. If we are sketching more than one relationship on a graph, we need to represent the different relationships relative to each other. To write a scenario from a sketch, we need to choose the variables and label the variables on the axes. Then we can write the scenario to match the line or curve of the graph. Sample Daily Lesson- Teacher Lesson Plan Guided Practice: We have three containers of different sizes and shapes shown. Water is poured into each container at the same constant rate. The graph below shows how the height of water varies as the volume of the water increases for container A. On the same graph sketch the height-volume relationship for containers B and C. We need to label each line. Container B is half the height of container A and container B is also narrow, the height of the water will increase at a greater rate and the total volume will be less when filled. Since the sides of the container are vertical, we also have a line. We draw the line on the graph accordingly. You need to write this justification next to the graph in the space provided. Let s sketch the height-volume relationship for container C. The bottom of container C is wider than container A so the rate of the water s height increase will be less at first. Once the height of the water reaches the upper portion of the container, the height will increase at the same rate as it did for container B. This change is captured in the sketch by changing the slope of the line. The heights of containers A and C are equal but the volume of container C is greater. So we stop our line at the same height but reflect a greater volume by sketching the line further to the right. Select students to explain why the graph looks the way it does. Independent Practice: In these practice problems, you have to think in the other direction. You are given the graph, and you need to write a scenario. It is very important that you define your variables. Label each axis. There is no one correct answer. There are infinitely many correct answers, but there are incorrect answers. Your scenario must match your graph and use the variables you chose. Review: Have the students exchange their scenarios and have other students read, and if needed, correct each other s scenarios. When the students are finished, go over the problems. Select students to share their scenarios. Closure: Today we sketched graphs from a verbal description and model. We also described the relationship between two quantities given a graph. We had to determine and label the variables on the graph. Answers: Answers will vary for all problems. 1. Mike is one mile from home. He rides his bike further from home at a constant speed. The y- axis of graph should be labeled as distance and x-axis should be labeled time. 2. The height of a baby increases slowly at first. The baby has a growth spurt, and its height increases rapidly. The baby s increase in height slows down again. The y-axis should be labeled height and the x-axis should be labeled time. 3. Yolanda increases her speed while riding her bike. Once she reaches a certain speed, she travels at a constant speed. She then peddles up to a hill, and her speed decreases until she is barely moving. She reaches the top of the hill where the road is flat, and she travels at a much slower constant speed since she is tired from climbing the hill. Once she reaches her destination, she stops. The y-axis is labeled speed and x-axis is labeled as time. 16 www.standardsplus.org - 1.877.505.9152

Common Core Standards Plus Mathematics Grade 8 Domain: Functions Focus: Describe Functional Relationships Lesson: #22 Standard: 8.F.5: Describe qualitatively the functional relationship between two quantities by analyzing a graph (e.g., where the function is increasing or decreasing, linear or nonlinear). Sketch a graph that exhibits the qualitative features of a function that has been described verbally. Lesson Objective: Students will analyze graphs and interpret their meaning by answering questions. Introduction: Today we will continue to analyze function graphs and interpret their meanings to answer questions and justify our answers. Instruction: To be able to interpret function graphs, we must pay attention to the variables as defined by the axes labels, the characteristics of the function graph such as increasing or decreasing, linear or non-linear, and the behavior of the function in relation to another function that is sketched on the same graph. Sample Daily Lesson- Teacher Lesson Plan Guided Practice: Let s complete the example together. The graph below shows how the speed of a racing car varies during the second lap of a raceway. What do you notice about the speed as the car travels around the second lap? The car slows down three times as it travels around the lap of the raceway. Does it slow down the same amount each time? No, it slows down the most during the second time and it slows down the least during the third time. When would a race car slow down on a raceway? As it s going around a curve or corner. How many curves do you think this raceway has? (3) How do you know? The graph shows the car slowing down three times. Now think about how the sharpness of a curve must look relative to the other curves by looking at the speed graph. You have five potential raceway circuits that the race car could be traveling. Point s represents where the race car would be at the start of the second lap. Which of these circuits was the racing car going around? Carefully examine each circuit. You should be able to justify your selection. Which circuit did you choose and why? You should have selected circuit B. Circuit B has three curves. But so does circuit C. Why is B a better choice than C? Notice that the second curve is the sharpest and would require the greatest reduction in speed and the third curve is the least sharp as compared to the other curves, and would require the least amount of speed reduction. This matches the speed-distance graph. Independent Practice: It s your turn to apply the same process as we did together in the example. You will analyze a graph and answer questions and justify your thinking. Review: When the students are finished, go over the problems. Closure: Today we analyzed function graphs and interpreted their meaning to answer questions and justify answers. Answers: 1. Car 2 travels a greater distance. Both cars start and stop at the same time. Car 2 travels faster than car 1 the entire time so therefore it travels farther. 2. Car 1 is traveling at a constant velocity between points E and F. 3. Car 1 accelerates two times. The first time is between points A and B. The second time is between points C and D. We know the car is accelerating because the velocity is increasing between these two sets of points. 4. Car 2 is accelerating between points A and I. It is accelerating greater between points A and H than between points H and I because the slope of the line segment between is A and H is steeper than the line segment between H and I. 18 www.standardsplus.org - 1.877.505.9152

Common Core Standards Plus Mathematics Grade 8 Domain: Functions Focus: Describe Functional Relationships Lesson: #23 Standard: 8.F.5: Describe qualitatively the functional relationship between two quantities by analyzing a graph (e.g., where the function is increasing or decreasing, linear or nonlinear). Sketch a graph that exhibits the qualitative features of a function that has been described verbally. Sample Daily Lesson- Teacher Lesson Plan Lesson Objective: Students will analyze graphs and answer questions about the scenario the function represents. Introduction: Today we will continue to analyze function graphs and interpret their meaning to answer questions and justify our answers. Instruction: To be able to interpret function graphs, we must pay attention to the variables as defined by the axes labels, the characteristics of the function graph such as increasing or decreasing, linear or non-linear, and the behavior of the function in relation to another function that is sketched on the same graph. Today we will have only one function sketched on the graph. Since our functions are graphed on axes with a scale, we must pay close attention to the scale and read the numbers correctly. Guided Practice: A farmer is building a rectangular animal pen. She purchases 50 feet of fencing, and she wants to use all 50 feet of fence. The graph on your page represents the relationship between the possible widths and corresponding areas of the pen assuming the farmer uses all 50 feet of fencing. The labeled point represents the maximum point on the graph. The first question asks what are the possible widths of the pen if it is 100 square feet? The possible widths for a 100-square foot area pen are 5 feet and 20 feet. We can determine this by drawing a horizontal line through the graph at 100 square feet and seeing where the horizontal line, represented by the equation y = 100, intersects with the curve. It intersects in two locations. It intersects at x = 5 and at x = 20. At what range of widths does the area increase? The area increases until it reaches the maximum value on the graph. The point marked and labeled on the graph represents the maximum area and at what width that occurs at. Therefore, as the widths increase from 0 to 12.5 feet, the area also increases. What is the maximum area of the pen possible? The maximum area is 156.25 square feet. What are the dimensions of the pen with the maximum area? We know the width. It s12.5 feet. We have to calculate the length. Since the pen is rectangular, we divide the area by the width to find the length. 156.25 divided by 12.5 is 12.5. This tells us the rectangle which the largest area is a square. We can use the graph to find other possible widths by drawing a horizontal line through any other area and finding the two intersections points with the curve. The intersection points will represent the widths. Once we identify the widths, we can calculate the length. We can only approximate the width since there are no other points that fall on the graph that are integer points. I will choose the area to be 140 square feet. If I draw a horizontal line through 140 square feet, the two points it intersects through are approximately x = 8.5 and x = 16.5. So if the width is 8.5 feet then by calculation, the length is about 16.5 feet since 140 square feet divided by 8.5 is about 16.5. If the width is 16.5 feet, then the length is 8.5 feet. Independent Practice: It is your turn to complete the practice problem. Notice the labels and scale on the axes. You will need to interpret these correctly to accurately answer the questions. Review: When the students are finished, go over the problems. Closure: Today we analyzed function graphs and interpreted their meaning. Answers: 1. 1.5 meters 2. 15.5 meters 3. 7 meters. 15.5 1.5 = 14. 14 is the diam. Half the diam. is the radius, so half of 14 is 7. 4. 16 seconds. You can see the time it takes the Ferris wheel to go from its max. height to the next time it reaches its max. height (or any combination of time to complete 1 revolution). 5. Two times. 32 seconds has passed between points A and B. Since it takes 16 seconds for one complete revolution, it will have completed 2 revolutions in 32 seconds. 20 www.standardsplus.org - 1.877.505.9152

Common Core Standards Plus Mathematics Grade 8 Domain: Functions Focus: Describe Functional Relationships Lesson: #24 Standard: 8.F.5: Describe qualitatively the functional relationship between two quantities by analyzing a graph (e.g., where the function is increasing or decreasing, linear or nonlinear). Sketch a graph that exhibits the qualitative features of a function that has been described verbally. Lesson Objective: Students will analyze graphs and answer questions about the scenario the function represents. Introduction: Today we will continue to analyze function graphs and interpret their meaning to answer questions and justify our answers. Instruction: We have been interpreting function graphs by noting several things: the variables defined by the axes labels; the characteristics of the function graph as increasing, decreasing, linear, or non-linear; and the behavior of the function in relation to another function that is sketched on the same graph. Today only one function will be sketched on the graph. Since our functions are graphed on axes with a scale, we will note the scale and read the numbers correctly. Sample Daily Lesson- Teacher Lesson Plan Guided Practice: Let s complete the example together. You have a graph that represents the relationship between the height of a ball in feet and time in seconds. The x-scale is by ones and the y-scale is by tens. The first question asks what time does the ball reach its maximum height? Where do we look on the graph to find the answer? Yes, we look at the maximum height which is the maximum point on the graph. The maximum height occurs at 3 seconds. What is the speed of the ball at the maximum height? Be careful. We are not given speed on the graph. Think about this. Between zero and three seconds, the height of the ball is increasing. Between three and six seconds, the height of the ball is decreasing. What is the speed at the moment the ball reaches it maximum height? Yes, it s zero. The ball comes to a stop before it comes back down. We know this because it changes from the increasing height to decreasing height. What is the height of the ball at 4 seconds? It is close to 128 feet. At 5 seconds? The ball is at 80 feet. At 6 seconds? It s at zero height. So between 4 and 5 seconds the ball travels 48 feet. Between 5 and 6 seconds, the ball travels 80 feet. So is the speed of the ball increasing or decreasing between 3 and 6 seconds? Yes, it s increasing. We know this because the change in height over the same change in time increases. Independent Practice: It s your turn to apply the same process and complete the practice problem. Be sure to interpret the scale correctly. Review: When the students are finished, go over the problems. Closure: Today we analyzed non-linear function graphs and interpreted their meaning to answer questions and justify our answers. Answers: 1. 10 feet. 2. Between 0.5 second and 1 second. About 0.75 second. 3. 10 bounces. 4. About 9 seconds. At that time it appears the line is flat. 5. After each bounce the ball decreases in height and the time between bounces becomes shorter. 6. To determine the total vertical distance the ball travels, add up the maximum height of each bounce and multiply it by two, then add in the initial height. 7. The maximum height changes non-linearly. You would draw a curve, not a line, connecting the maximum heights of each bounce. 24 www.standardsplus.org - 1.877.505.9152
