Graphing Linear Functions

Grade Level(s):  8^th – 9^th Grade

Content Area:                                                                        Process Area:

Numbers and Operations                                           Problem-Solving

Algebra                                                           Reasoning and Proof

Geometry                                                                    Communication

Measurement                                                             Representation

Data Analysis, Statistics, and Probability                    Connections

Common Core Standards:

CCSS.MATH.CONTENT.8.EE.C.8: Analyze and solve pairs of simultaneous linear equations.

·         CCSS.MATH.CONTENT.8.EE.C.8.A: Understand that solutions to a system of two linear equations in two variables correspond to points of intersection of their graphs, because points of intersection satisfy both equations simultaneously.

·         CCSS.MATH.CONTENT.8.EE.C.8.B: Solve systems of two linear equations in two variables algebraically, and estimate solutions by graphing the equations. Solve simple cases by inspection. For example, 3x + 2y = 5 and 3x + 2y = 6 have no solution because 3x + 2y cannot simultaneously be 5 and 6.

Targeted Needs of Student:

Graphing equations, understanding the importance of neat work with equations, understanding slope and linear functions, self-checking answers

Goal:

To practice how to graph equations with lines

Materials Needed:

1.      Worksheets

2.      Rulers

3.      Pencils

4.      Scratch Paper

Explanation/Summary:

Students will graph each of the lines that are in slope intercept form on the coordinate plane with letters on it. As they graph, letters and numbers will be hit by the same line. Then they will write the corresponding letter with the letter on the bottom of the page to answer the question, “What’s green and fluffy and comes from outer space?”
