Students of all levels continually struggle with word problems; however, there is a solution to this "problem". The objective for this curriculum unit is to show students the multiple ways that system of equations can be used to solve real-world problems.

In order for students to be engaged and interested in learning, they need to see the real-world practicality behind the math concept being learned.

Without a lot of practice, System of Equations can be difficult for students to compute correctly and efficiently. When difficulty is combined with a lack of interest or a question of relevance, the student can become frustrated and disengaged. Therefore, in order to capture the attention and interest of my students, I will first discuss what a system of equations is and then explain how to solve one using three different methods.

This will undoubtedly be of interest to any student. Then I will combine the distance and interest formulas together with a system of equations and demonstrate how to solve real-world scenarios and exciting problems. I will also provide practical examples of problems involving wind and water currents, chemistry problems involving mixtures and solutions, more interest problems involving the time value of money, and other practical examples that involve systems of equations.

I will spend two days on each of the three methods. Next, I will spend another three or four days introducing the interest and distance formulas, incorporating them into system of equations.

It is critical that the students get a feel for solving the problems before I introduce the more complicated word problems. The distance formulas and simple interest formulas are not extremely complicated, and my students typically pick up on them quickly.

I have also introduced them earlier in the year and use them as warm-up problems several times per week. The first system of equations I will introduce is one that will require the substitution method to solve.

Together they have songs. How many songs does each person have? Therefore, if we subtract the first equation from the second equation we will be able to isolate the y variable.

How many lawns did they each cut? An example of a word problem that we could use the multiplication elimination method to solve is: In this particular class, I have relatively few behavior problems.

Talking at inappropriate times is my students' biggest fault. Carmel Middle School is on a block schedule and my Algebra class meets every day for approximately 85 minutes.

I have a pacing guide, created by the county I teach in, that I follow. There is not an abundance of time allocated for systems of equations, so I tend to move rather quickly.

I typically have about 30 students in an Algebra class and I have approximately 20 to 25 students in my lower level classes. The population at my school is as follows: Twenty six percent of our students are enrolled in the Gifted and Talented program, while These percentages put us above the Charlotte Mecklenburg District average in both categories.

The District itself is growing larger and larger every year; it currently enrollsstudents and employs 10, teachers. Over the last couple of years, the Charlotte-Mecklenburg School System has increased the number of students by approximately 6, students per year.Creating a Standard Curve Create a standard curve by graphing the following data (Absorbance vs.

Protein Concentration). Be Draw a line of best fit. A line of best fit (or "trend" line) is a straight line that best represents the data on a scatter plot.

This line may pass through some of the points, none of the points, or all of the points. Approximately billion pounds of milk was sold in the U.S. in , with skim and low-fat milk making up the largest milk category by accounting for approximately 55 percent of the sales that.

Generally, the amount of tip you pay for a service is a linear function of the amount you are billed. For example, it is said to be generally acceptable to tip 15% of your bill at restaurants in the US (Gratuity).

Write a linear inequality in two variables to represent the number of minutes you can use for calls within the United States and for calls to Mexico.
