Lesson 34 writing and graphing inequalities in real-world economics

To do this, I will present my students with two problems that I will work out step by step. The modeling of these two problems will later serve as a reference to the successful completion of the independent practice. Using these problems, I will allow student to ask questions and address any misconceptions that they may have at this time.

We will discuss this until the information we need to correctly graph the relation is identified, but I will not specifically point out that we will be making the line solid, rather than dotted. The commands will be presented on a card of some sort.

Graphing Linear Inequalities

When I read their scenario, they will come to the front of the classroom with their paddles and present their answers.

Then write a mathematical scenario that can be solved using the one - step inequality that you have chosen. We will then review our responses as a whole group. Then, we will work as a class to test the points by plugging them into the original inequality.

The students that I choose for the second problem will be selected using a purposeful method, in that, they will be chosen to showcase the many different ways that the students could have solved this particular problem.

Writing and Graphing Inequalities in Real-World Problems

She cannot decide whether she wants to buy or pack her lunch. Analyze the relationship between the dependent and independent variables using graphs and tables, and relate these to the equation.

Then, I will ask three students to provide me with solutions to the second problem. Then write a word problem that result in the inequality that you have written with a solution greater than 8.

One problem is a word problem that involves inequalities. We will follow the same process as the previous example.

Inequalities in the Real-World

If you were to draw a line that is longer than 10 inches, how long would that line be? If you were to walk part of the width of the classroom, and the classroom is 40 tiles wide, to what tile number would you walk? After these students have presented their answers and we have had the discussion as to why there is more than one solution to the scenario being presented at that time, I will then ask all students what are some other possible solutions.


If you jump, as high as you can, no less than 7 times, how many times would you jump? The other problem is one that will require me to work backwards to create an inequality word problem. The problems that my students will try are as follows: A student will then read the objective, "SWBAT represent the solution to a linear inequality on the coordinate plane.

Curriculum Reinforcer 5 minutes The curriculum reinforcer, is a daily practice piece that is incorporated into almost every lesson to help my students to retain skills and conceptual understanding from earlier lessons. I will then ask six volunteers to come up to the board to draw a sketch on their graph for the class.

How much money would you keep in your account? They will have to carry out each command while taking into consideration that limitation. After the allotted time has elapsed, I will ask my students to provide the solution to the first problem.

Every student will be given a whiteboard paddle to write their answers on. How long could your object be? The cards will have the following scenarios written on them: Write a one - step inequality that has a solution less than 7. At this point I will introduce the word boundary line, and ask students to add solid and dashed lines to the table at the top of their notes below the corresponding inequality symbols.

Write and solve an inequality to find the maximum number of letters he can have engraved. For this reason, all students should be taking notes during this time. After they share some ideas I will ask: After each test, we will label the points on the graph using the word true or the word false.

Students can choose to work independently or with a partner, but will be required to compare their work with a peer every 10 minutes.

How does the presence of an inequality symbol in our current example effect the graph of the solution? Write a one-step inequality that has a solution greater than 8.Free step-by-step solutions to Algebra 1 () - Slader.

Lesson Writing and Graphing Inequalities in Real-World Problems Date: 4/3/14 S © Comm. Use variables to represent numbers and write expressions when solving a real-world or mathematical problem; understand that a variable can represent an unknown number, or, depending on the purpose at hand, any number in a specified set.

Lesson Writing and Graphing Inequalities in Real‐World Problems Student Outcomes Students recognize that inequalities of the form T O?

and T P?, where T is a variable and? is a fixed number have infinitely many solutions when the values of T come from a set of rational numbers. Lesson 34 (6th grade) -Writing & Graphing Inequalities in Real World Problems Write an inequality and graph on a number line.

On problemswrite an inequality, solve for variable using the 7 steps of algebra and graph on a number line. Title: Lesson Writing & Graphing Inequalities Author.

Students recognize that inequalities of the form 𝑥𝑥 𝑐𝑐, where 𝑥𝑥 is a variable and 𝑐𝑐 is a fixed number, have infinitely many solutions when the values of 𝑥𝑥 come from a set of rational numbers.
