13Day Two Lesson PlanLesson Topic: Using InterceptsGrade Level: 9Materials: TI-83 plus calculator, Overhead with calculator adaptor, InstructionWorksheet (graphing), Instruction Worksheet (finding intercepts), X-Y InterceptsWorksheet.Lesson Overview: Students will work with their calculators to develop an understandingof intercepts.Lesson Objectives:• Students will be able to graph linear equations.• Given linear equations, students will calculate the x and y intercepts on the graph.• Given linear equations, students will be able to draw conclusions about linearequations and their intercepts.• A.A.21- Determine whether a given value is a solution to a given linear equationin one variable or linear inequality in one variable.New York Standard:• A.CM.1 – Communicate verbally and in writing a correct, complete, coherent,and clear design and explanation for the steps used in solving a problem.• A.CM.5 – Communicate logical arguments clearly, showing why a result makessense and why the reasoning is valid.• A.R.3 – Use representation as a tool for exploring and understandingmathematical ideas.NCTM Standards:• Understand patterns, relations, and functions.• Organize and consolidate their mathematical thinking through communication.• Communicate their mathematical thinking coherently and clearly to peers,teachers, and others.• Analyze and evaluate the mathematical thinking and strategies of others.• Create and use representations to organize, record, and communicatemathematical ideas.Anticipatory Set: The teacher will begin class with a few questions:1. What does intercept mean?2. How many intercepts do you think there are in graphing a line?3. What do you think intercepts represent in graphing a line?Possible Responses:1. When something crosses something, where they cross is the intercept2. 1 or 23. Where a line crosses the axis
