14 Teacher Lesson Plan Standards Plus Common Core Intervention Mathematics Grade 7 Domain: Expressions & Equations Focus: Solve & Graph Linear Equations Lesson: # 12 Lesson Objective: Solve and graph linear equations. Introduction: Students will use linear equations to complete x and y tables. Then, they will write the coordinate pairs defined in the tables. Finally, they will graph the line defined by the linear equation. Instruction: Today you will use linear equations to complete x and y tables. Here is an example of an x and y table and a linear equation. In this table, we see 6 in the x column. Next to the 6 is a 5 in the y column. Then, we have (5, 4), (4, 3), and (3, 2). The linear equation says, y = x 1. In each row, did they subtract 1 from x to find y? Yes. Guided Practice: Now, notice that the coordinate pairs are given. We will graph these coordinate pairs. Let s begin with (6, 5). The 6 is the x value, so we will move horizontally along the x axis to 6. Then, we ll move vertically up to 5. This is where we place the first point. Next, we will graph (5, 4). Let s move horizontally across to five, and vertically up to four. Draw the point. (Repeat with the remaining points.) Now, let s connect the points to make the line. Independent Practice: There are two more tables for you to try. Remember, You must use the linear equation to determine each missing value. Then, write the coordinate pairs and graph them on the coordinate plane. Review: After a few minutes, review together. St. Ed. pg. B18 Closure: Today you determined the missing values in tables and wrote coordinate pairs to match the values using the given linear equations. Then, you graphed the linear equation. Answers: 1. (1, 2), (2, 4), (3, 6), and (4, 8); graphed line should begin at (1, 2) and extend up to the right to (4, 8). 2. (3, 2), (4, 3), (5, 4), and (6, 5); graphed line should begin at (3, 2) and extend up to the right to (6, 5). 14

Introduction: Students will read problems, complete tables, and write linear equations to explain situations. Instruction: Today you will read problems and create x and y tables to fit the problem situations. Then you will write the linear equation that fits each situation. Guided Practice: Let s look at the example. Vera has tomato plants in her garden. Each plant produces 12 tomatoes. Make a table to show the number of tomatoes (x) produced by 5, 10, 15, and 20 plants (y). Below this problem, we see a table that has been started for us. Look at the first row. When Vera has 5 plants, they produce 60 tomatoes. When she has 10 plants, how many tomatoes do they produce? (120) When she has 15 plants, how many tomatoes do they produce? (180) When she has 20 plants, how many tomatoes do they produce? (240) The linear equation is x = 12y. This means that to find x, we multiply y by 12. Independent Practice: Create a table and write the linear equation for each of the given situations. Review: After a few minutes, review together. Closure: Today you completed tables and wrote linear equations for problem situations. St. Ed. pg. B19 Answers: 1. (125, 5); (250, 10); (375, 15); (500, 20); x = 25y 2.

Introduction: Students will read problems, complete tables, and write and graph linear equations to explain situations. Instruction: Today you will read problems and create x and y tables to fit the problem situations. Then you will write the linear equation that fits the situations presented. Guided Practice: Let s look at the example. Vera has tomato plants in her garden. Each plant takes up 2 square feet in the garden. Make a table to show the number of square feet (x) required to grow 2, 5, 10, and 25 tomato plants (y). Write the linear equation. Then, graph the line on the coordinate grid.

22 Teacher Lesson Plan Standards Plus Common Core Intervention Mathematics Grade 7 Domain: Expressions & Equations Focus: Determining Slope Lesson: # 16 Lesson Objective: Interpret the slope of a line. Introduction: Today students will learn the meaning of slope and determine the slope of given lines. Instruction: One important property of straight lines is how they angle away from the horizontal. The x axis on the coordinate plane is a horizontal line. The slope of a horizontal line is zero. Vertical lines have no slope because they do not angle in a positive or negative direction from the horizon. All other lines have a slope that is positive or negative. To find the slope of a line, we must know the location of two points on the line. For this line, the two points are at (1, 2) and (5, 6). We use the y1 y2 formula m= to determine the slope of the line. The variable m represents the x x 1 2 slope. We see y 1 y 2. This means the y coordinate in the first coordinate pair minus the y coordinate in the second pair. We see x 1 x 2. This means the x coordinate in the first coordinate pair minus the x coordinate in the second pair. We divide to solve. Guided Practice: Let s find the slope for a line that has these two points: (1, 2) and (5, 6). We solve the problem like this: m= = = What is the slope of a line that has these two points: (2, 6) and (5, 2)? We have 6 2 divided by 2 5, so we have 4 divided by 3. What is the slope? 4 3 St. Ed. pg. B22 Independent Practice: Determine the slope of lines that contain the given points. Review: After a few minutes, review together.

26 Teacher Lesson Plan Standards Plus Common Core Intervention Mathematics Grade 7 Domain: Expressions & Equations Focus: Inequalities Lesson: # 18 Lesson Objective: Identify, solve, and graph inequalities. Introduction: Students will write inequalities today. Instruction: Today you will write inequalities. When we write equations, we use an equal sign because what comes on the left of equation is equal to what comes on the right of an equation. When we write inequalities, we use the less than, less than or equal to, greater than, or greater than or equal to symbols because the two sides are not equal. Look at you paper. Here are the four symbols we use when writing inequalities. (Point out the four symbols at the top of the page.) Here is an example of an inequality: a number 7 is less than 22. n 7 < 22. Guided Practice: Let s look at the example. A number +5 is greater than 12. We will use n as the variable, so let s write n. Then it says + 5. Let s write + 5. It says is greater than. What symbol do we use? (>) We write the greater than symbol. Finally, it says 12. Our inequality should read n + 5 > 12. Make sure you have written the inequality correctly on your paper. Independent Practice: There are six problems for you today. Remember, use the less than, less than or equal to, greater than, or greater than or equal to symbols to write the inequalities.

Here is an example of an inequality: a number + 14 is less than or equal to 6. n When we solve inequalities, we isolate the variable. In this example, we isolate the variable by subtracting 14 from both sides: n n 8. So, in this situation n is less than or equal to 8. Guided Practice: Let s look at the example. A number + 43 is greater than 9. We will use n as the variable, so let s write n. Then, it says Let s write It says is greater than. What symbol do we use? (>) We write the greater than symbol. Finally it says 9. Our inequality should read n + 43 > 9. Now we solve by subtracting 43 from both sides to isolate the variable. Now we have n > We simplify: n > 52.

32 Teacher Lesson Plan Standards Plus Common Core Intervention Mathematics Grade 7 Domain: Expressions & Equations Focus: Solve and Graph Inequalities Lesson: # 21 Lesson Objective: Demonstrate an ability to write, solve, and graph inequalities. Introduction: Students will solve and graph inequalities in today s lesson. Instruction: Today you will solve and graph inequalities. When we solve equations, we end up with a line, but when we solve an inequality, there are many possible answers. We will learn how to show the possible answers in today s lesson. When we graph the inequalities, we will use a number line. It is important that you carefully note if the inequality symbol is greater than or less than OR greater than or equal to or less than or equal to. When we say 7 > n, 7 is not a possible answer. When we say 7 n, 7 is a possible answer. Guided Practice: Let s look at the example. 3 > n 4. We must multiply both sides by 4 to isolate the variable. 3 4 > n > n. Look at the number line. We must graph 12 > n. We do so by showing an open starting place at 12. Then, we darken the number line to the left of 12. This is to show than any number smaller than 12 correctly answers the inequality. If the inequality had been greater than or equal to, we would have darkened the starting place at 12 to include it as a possible answer. Independent Practice: There are four inequalities for you to solve in today s lesson. Solve each inequality and graph it on the number line. Review: After a few minutes, review together. Closure: Today you solved and graphed inequalities. St. Ed. pg. B27 Answers: 1. n 10; n; n < 40; > n;

Introduction: Students will use inverse operations to solve problems in today s lesson. Instruction: An equation is a mathematical sentence with an equal sign. In an equation such as m + 5 = 27, a value of the variable that makes the equation true is called a solution. We can use inverse (opposite) operations to solve for the variable. We can solve equations using inverse operations. To solve or undo an addition equation, we will use subtraction. To solve or undo a subtraction equation, we will use addition. Guided Practice: Let s solve the examples together. Example A says m + 5 = 27. We isolate the variable by subtracting 5 from both sides of the equation: m = We simplify, so m = 22. We check by substituting the solution for the variable: = 27. Example B says k 3.6 = 4.2. We isolate the variable by adding 3.6 to both sides of the equation: k = We simplify, so k = 7.8. We check by substituting the solution for the variable: = 4.2. Independent Practice: Use inverse operations to solve each problem. Review: After a few minutes, review together. Closure: Today you used inverse operations to solve problems. Answers: St. Ed. pg. B28 34

Introduction: Students will use inverse operations to solve problems in today s lesson. Instruction: An equation is a mathematical sentence with an equal sign. In an equation such as 3n=27, a value of the variable that makes the equation true is called a solution. We can use inverse (opposite) operations to solve for the variable. We can solve equations using inverse operations. To solve or undo a multiplication equation, we will use division. To solve or undo a division equation, we will use multiplication. Guided Practice: Let s solve the examples together. Example A is 6m = 42. We divide both sides of the equation by six to isolate the variable: 6m 6 = We simplify, so m = 7. We check by substituting the solution for the variable: 6 7 = 42. Example B is 7 r = 6. We multiply both sides of the equation to isolate the variable: 7 r 7 = 6 7. We simplify, so r = 42. We check by substituting the solution for the variable: 42 7 = 6. Independent Practice: Use inverse operations to solve each problem. Review: After a few minutes, review together.
