5- Day Lesson Plan Unit: Linear Equations Grade Level: Grade 9 ...

7Grade Level: 9Materials: Geometer’s Sketchpad, Worksheets, Computers, JournalsLesson Overview: Students will work with Geometer Sketchpad to develop anunderstanding of graphing linear equations..Lesson Objectives:• Students will demonstrate how to make a table of values.• Students will be able to graph linear equations in Geometers Sketchpad.New York Standards:• A.R.1 – Use physical objects, diagrams, charts, tables, graphs, symbols, equation,or objects created using technology as representation of mathematical concepts.• A.R.3 – Use representation as a tool for exploring and understandingmathematical ideas.• A.G.4 – Identify and graph linear functions• A.A.21- Determine whether a given value is a solution to a given linear equationin one variable or linear inequality in one variable.NCTM Standards:• Create and use representations to organize, record, and communicatemathematical ideas.• Use Mathematical models to represent and understand quantitative relationships.Anticipatory Set: The teacher will open the class by asking a variety of differentquestions that pertain to graphing linear equations:1. What makes up a line?2. How many points make up a line?3. If you are given a linear equation, what information would you need from theequation inorder to graph it?Possible Responses:1. A line consists of points2. 2 points make a line3. PointsDevelopmental Activity:1. The teacher will discuss with the students how to find the values of points ona linear equation by creating a table and solving for different values. Theteacher will show the students an example of a linear equation and set up atable on the overhead. Then the teacher will show the students how to find thevalues, by algebraically solving for y when placing different numbers in for x,while using the overhead. (Worksheet)
