## Translate between verbal and symbolic representations of real-world phenomena involving linear equations. SPI 0706.3.7

1. Application of Linear Equations - this page is about a topic that most students hate, applications of linear equations - in other words story problems or word problems
2. Fun and Sun Rent-a-Car - students use tables, graphs, linear functions to solve a real-world problem 3. Graphing Linear Equations - introduction followed by an in-depth explanation, examples and two pages of practice questions 4. Graphing Linear Equations: Making a T-chart (finding plot points) - four pages of instructions with several examples and illustrations
5. Internet Project - let your cursor hover over the Assess button and select Internet Project - Students will collect data and then make a scatter plot and a best fit line, find the slope, y-intercept and the equation of a line [This expired link is available through the Wayback Machine Internet Archive. If the page doesn't load quickly click on Impatient? at the bottom right of the page.] 6. Linear Equation Solver - [advanced] a java applet which lets your students enter variables [three equations, three unknowns] 7. Linear Equation Solver - select from three types of equations 8. Linear Equations in one Variable - Quia game quiz which asks students to solve one- and two-step linear equations and simple algebraic proportions as they work toward winning \$1,000,000. 9. the intermediate step(s), provide the answer to the equation and show how to verify the answer [This expired link is available through the Wayback Machine Internet Archive. If the page doesn't load quickly click on Impatient? at the bottom right of the page.] 10. Ratio/Proportion Problems from Ask Dr. Math - three pages of links to real-world problems
11. Representations of Linear Functions: Cab fares - The charge for a cab ride is determined by the length of travel. Some companies also charge a basic, fixed amount. At this site you will find descriptions of fares of three competing cab companies and you are asked to suggest a new fare.
12. Slope-Intercept Form - [12 slides] this show uses animation very effectively, provides examples and the chance for student response and invludes a great real-world application of slope-intercept [This expired link is available through the Wayback Machine Internet Archive.

13. Slope Intercept Jeopardy - this show is in Jeopardy format; with five categories each with five questions - good for a while class review
14. Solving Linear Equations - explanation provided by Study Guides and Strategies
15. Solving Linear Equations - seven practice problems, solutions available for each problem 16. Solving Multi-Step Linear Equations - this two page explanation from Purple Math includes a large number of examples
17. Using the X and Y Intercept to Graph Linear Equations - This follow up to the lesson on rate of change deals with linear equations written in standard form rather than slope intercept form Internet4classrooms is a collaborative effort by Susan Brooks and Bill Byles.
