2<strong>Unit</strong> ObjectivesGiven a five day instruction on linear equations, the following are unit objectives:• Given instruction on how to create a table of values on the calculator from a linearequation, students will demonstrate how to make a table of values.• Given technology instruction on how to use Geometers Sketchpad, students willbe able to graph linear equations in Geometers Sketchpad.• Given a technical briefing on the TI-83 calculator, the students will be able tograph linear equations with their calculators.• Students will calculate the x and y intercepts on the graph given linear equations.• Students will create graphs and describe their slopes given instruction on theCBR.• 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 find the slope.• Given the slope-intercept formula, the students will be able to rewrite linearequations into the slope-intercept form.• Using the Green Globs software the students will be able to write linear equations.• Given the slope and a point on the line, students will be able to write linearequations.• Given a technical briefing of the TI-83 calculator, students will be able to entersystem of equations into the calculator.• Given instruction on the matrix program of the TI-83 calculator, students will beable to solve systems of equations.• Students will be able to explore equations on the calculator by graphing the linearequations.New York State Standards
3Standard 3: Mathematics• 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, function, equations, charts,graphs, Venn diagrams, and other diagrams.• A.R.3 – Use representation as a tool for exploring and understandingmathematical ideas.• A.G.9 – Solve system of linear equations graphically.• A.R.1 – Use physical objects, diagrams, charts, tables, graphs, symbols, equation,or objects created using technology as representation of mathematical concepts.• A.G.4 – Identify and graph linear functions• Given a technical briefing on the TI-83 calculator, the students will be able tograph linear equations.• A.PS.4 – Use multiple representations to represent and explain problemsituations.• A.A.33 – Determine the slope of a line, given the coordinates of two points on theline.• A.A.34 – Write the equation of a line, given its slope and the coordinates of apoint on the line.NCTM Standards• Create and use representations to organize, record, and communicatemathematical ideas.• Use Mathematical models to represent and understand quantitative relationships.• 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.• Represent and analyze mathematical situations and structures using algebraicsymbols.• Apply and adapt a variety of appropriate strategies to solve problems.Resources
