21Grade Level: 9Materials: Calculator-Based Ranger (CBR 2), Overhead with TI-adapter, TI-83 plusCalculator, Graph paper, CBR Worksheet 1, Homework Worksheet, Journals, Pencil.Lesson Overview: Students will work the CBR to develop an understanding of slope.The students will also be introduced to the slope formula to compute slope.Lesson Objectives:• Given instruction on the CBR, the students will create graphs and describe theirslopes• Given the slope formula, students will be able to find the slope of a line.• Students will be able to describe slopes with appropriate mathematicalvocabulary.• Given the TI-83 calculators, students will be able to graph a linear equation andfind the slope.New York State Standards:• A.PS.4 – Use multiple representations to represent and explain problemsituations.• A.CM.2 – Use mathematical representations to communicate with appropriateaccuracy, including numerical tables, formulas, functions, equations, charts,graphs, Venn diagrams, and other diagrams.• A.R.3 – Use representation as a tool for exploring and understandingmathematical ideas.• A.A.33 – Determine the slope of a line, given the coordinates of two points onthe line.• A.A.32- Explain slope as a rate of change between dependant and independentvariables.NCTM Standards:• Understand patterns, relations, and functions.• Communicate their mathematical thinking coherently and clearly to peers,teachers, and others.• Use the language of mathematics to express mathematical ideas precisely.• Create and use representations to organize, record, and communicatemathematical ideas.Anticipatory Set: The teacher asks the students to answer the following question:Determine whether each statement is positive slope, negative slope or no slope1.
