7.EE.B.4

Use variables to represent quantities in a real-world or mathematical problem, and construct simple equations and inequalities to solve problems by reasoning about the quantities.

7.EE.B.4b

Solve word problems leading to inequalities of the form px + q > r or px + q < r, where p, q, and r are specific rational numbers. Graph the solution set of the inequality and interpret it in the context of the problem. For example: As a salesperson, you are paid $50 per week plus $3 per sale. This week you want your pay to be at least $100. Write an inequality for the number of sales you need to make, and describe the solutions. (Combine with 424)

Opener: As students enter the room, they will immediately pick up and begin working on the opener – Instructional Strategy - Process for openers. This method of working and going over the opener lends itself to allow students to construct viable arguments and critique the reasoning of others, which is mathematical practice 3.

Learning Target: After completion of the opener, I will address the day’s learning targets to the students. For today's lesson, the intended target is “I can set up, solve, and graph inequalities.” Students will jot the learning target down in their agendas (our version of a student planner, there is a place to write the learning target for every day).

Mastery Graph Inequalities Test

Inequalities Test: Today students will take the Inequalities Test. The test consists of 20 multiple choice questions, utilizing Mastery Connect. Being that this is a test day, students will be expected to persevere individually with problems to find correct solutions (mathematical practice 1), paying close attention to precision (mathematical practice 6) - as a silly misstep could result in a wrong answer or graph. The problems on the test require students to solve mathematical problems as well as apply inequalities to solve real world problems (mathematical practice 2 and 4).
