2. C SOLVING MULTI-STEP EQUATIONS Common Core Objective 8.EE.7

3. C I, THE STUDENT, WILL BE ABLE TO: 1. SOLVE EQUATIONS WITH LINEAR EXPRESSIONS WITH ONE SOLUTION, INFINITELY MANY SOLUTIONS OR NO SOLUTIONS (8.EE.7) 2. GIVE EXAMPLES OF AND IDENTIFY EQUATIONS AS HAVING ONE SOLUTION, INFINITELY MANY SOLUTIONS OR NO SOLUTIONS (8.EE.7) OBJECTIVE

4. WARM UP – Thursday, October 16 th 1.Nine more than four times a number is the same as one less than twice the number. Find the number. 2.A square and a triangle have the same perimeters. Find the value of x. Then find the perimeter. 3.Solve:6(n – 1) = 9(n – 4) 4.The length of a rectangle is 3 more than two times the width. If the perimeter of the rectangle is 78, what are the dimensions of the rectangle? x - 3 x x 8

5. True or False?

7. How many different values of x make the equation true?

8. Collaborative Activity: Always, Sometimes, or Never True? (30 Minutes) You will work in groups of three or four. Each group should have a Card Set: Equations, a pair of scissors, a large sheet of paper, a marker, and a glue stick. You will also need a pencil to use when writing your explanations. You will be considering a number of equations in the same way we have been solving equations. In your groups, you will produce a poster that will show each equation classified according to whether it is always, sometimes, or never true.

9. Always, Sometimes, or Never True? You will need to divide your sheet of paper into three columns and head separate columns with the words: What does always true mean? What does never true mean? How many examples does it take to prove that an equation is sometimes true? Always TrueSometimes TrueNever True

10. How will you work together?

11. Sharing Posters (10 minutes) 1.You are now going to critique each others’ posters. 2.In your groups, move to another table and look at their poster. 3.If you disagree with where an equation has been placed, put a circle around the equation and write three things (in pen): Why you disagree Which column you think the equation needs moving to. Why you think the equation belongs there. 4.Put a circle around your comments and write your initials next to them.

12. Let’s Summarize (15 minutes)  Give me an equation that is always true/sometimes true/never true.  Why did you put this equation in this column?  Did anyone put this equation in a different column?

13. TICKET OUT! – What did you learn? Using your technology, you will answer 3 questions in google drive. Go to my wiki page Under Math 8, click on the link under today’s PowerPoint/date called TICKET OUT Please only respond once to the questions. Your homework tonight is the half sheet titled: When are the equations true?
