Page 1 of 19 MCC@WCCUSD 011/02/2015 Grade Level/Course: Math 8 Lesson/Unit Plan Name: Solving Linear Equations with One Solution, No Solutions and Infinitely Many Solutions. Rationale/Lesson Abstract: The objective of this lesson is to give students an understanding of linear equations in one variable with one solution, infinitely many solutions, or no solutions. Students will be able to write an equation that can be used to determine the number of solutions of the form x=a, a=a, or a=b. Timeframe: 2-3 60 minute periods Common Core Standard(s): Analyze and solve linear equations and pairs of simultaneous linear equations. 8.EE.7 Solve linear equations in one variable. a. Give examples of linear equations in one variable with one solution, infinitely many solutions. Show which of these possibilities is the case by successively transforming the given equation into simpler forms, until an equivalent equation of the form x=a, a=a, or a=b results (where a and b are different numbers). Instructional Resources/Materials: Paper, Pencil, Warm-up (p.18-19), Index Cards (p.9), Graphic Organizer (p.2-8) and Answer Keys (p.9-17)

Common Core Standard(s): Analyze and solve linear equations and pairs of simultaneous linear equations. 8.EE.7 Solve linear equations in one variable. a. Give examples of linear equations in one variable with one solution, infinitely many solutions. Show which of these possibilities is the case by successively transforming the given equation into simpler forms, until an equivalent equation of the form x=a, a=a, or a=b results (where a and b are different numbers).
