28Day Four Lesson PlanLesson Topic: Writing an equation for a lineGrade Level: 9Materials: Computers, Green Globs Software, Homework handout, Pencil, Paper.Lesson Overview: Students will work with Green Globs software to develop anunderstanding of writing equations.Lesson Objectives:• Given the slope-intercept formula, the students will be able to rewrite linearequations.• 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 an equationof a line.New York State Standards:• A.R.1 – Use physical objects, diagrams, charts, tables, graphs, symbols,equations, or objects created using technology as representations of mathematicalconcepts.• A.A.34 – Write the equation of a line, given its slope and the coordinates of apoint on the line.• A.G.4 – Identify and graph linear functions.NCTM Standards:• Represent and analyze mathematical situations and structures using algebraicsymbols.• Understand patterns, relations, and functions.• Create and use representations to organize, record, and communicatemathematical ideas.Anticipatory Set: The teacher will ask the students to find the slope and y-intercept of alinear equation.1. x – y = -22. y = 6 – x3. 1 = 2x -yPossible Response:1. Slope = -1, y-intercept = -22. Slope = -1, y-intercept = 63. Slope = 2, y-intercept = -1Main Activity:
29Lecture/Activities1. The teacher will have a direct instruction on the overhead on the slopeinterceptform of an equation: y = mx + b.2. The direct instruction will have an example of rewriting an equationinto the slope-intercept form, on the overhead. The example will be:1 = 2x – y which can be written as y = 2x – 1.3. The teacher will then review with the students by discussion, wherethe slope and y-intercept can be found in an equation. For example inthe equation y = 2x – 1, the slope is 2 and the y-intercept is -1.4. The teacher will also show the students that if you are given a pointand the slope you can write a linear equation. For example if you aregiven the point (1, 2) and slope = 2 then the equation is y = 2x + 2.This example will be done on the overhead.5. The teacher will introduce the Green Globs program to the class. Theteacher will show the students how to type equations into the program,by doing an example.6. The students will work in the Linear and Quadratics Program. Withinthis program the students will work with lines.7. Green Globs will give the students a line on a graph. The students areto write the equation of the line. If they are right they can advance tothe next level. If they are wrong, the program will graph the line youtyped and the student’s can change your response so it is correct.8. With this activity the students are learning by discovering. They areexploring linear equations through the Green Globs program.Closure: At the end of the class the students can play the Green Globs game. In thisgame the students try to hit all the green dots on the graph paper by writing equations andgraphing them. If the line crosses through a green dot, the dot gets hit and you receivepoints. The more dots you hit with a line the more points you get. The top five studentswho get the most points will receive a cool mechanical pencil.Assessment: The students will first rewrite equations into the slope-intercept form in thehomework assignment. Then students will also have to write down the equation of a linefor each problem which will consist of a point on the line and the slope. (HomeworkWorksheet)Homework
