Subject Area__Math_____________ Grade Level_______7___________ Unit____Unit 6: Equations and Inequalities______________________________ Standard: Day 7.EE.4ab 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. a. Solve word problems leading to equations of the form px + q = r and p(x + q) = r, where p, q, and r are specific rational numbers. Solve equations of these forms fluently. Compare an algebraic solution to an arithmetic solution, identifying the sequence of the operations used in each approach. For example, the perimeter of a rectangle is 54 cm. Its length is 6 cm. What is its width? b. 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. Daily Learning Target 1 I can solve mathematical and real-life problems with one-step equations using addition and subtraction property of equality. Target Type K Formative Assessment Solve each equation using either addition or subtraction property of equality. 1.) 2.) 3.) 4.) 2 I can solve mathematical and real-life problems with one-step equations using multiplication and division property of equality. K X + 15 = 43 Y – 12 = 32 Z+½=¾ A – 2 ½ = 15 ¾ Solve each equation using either multiplication and division property of equality. 1.) 3R = 150 2.) Y/4 = 21.8 3.) ¾ R = 7/10 4.)
