Algebra 1 Bellman, Allan E. , Sadie C. Bragg, Randall I Algebra 1 Bellman, Allan E., Sadie C. Bragg, Randall I. Charles, William G. Handlin, Sr., and Dan Kennedy. Algebra 1. Upper Saddle River, New Jersey: Pearson Education, 2004. Print. This 800+ page textbook is a high school level algebra book. I chose this book because it is easy for students at the high school level to comprehend, and contains all of the topics necessary to be taught in an algebra course. While it is easy to understand and learn from, it also offers problems which challenge the above average students. It offers a variety of problems which fully demonstrate the importance of these topics and the subject of algebra.

Algebra Practice Workbook Prentice Hall Algebra Practice Workbook Algebra Practice Workbook Prentice Hall Algebra Practice Workbook. Upper Saddle River: Prentice-Hall, 1998. Print. This practice workbook by Prentice Hall gives the students an excellent opportunity for more practice with solving these types of problems. Seeing that this workbook is also by Prentice Hall, just like the textbook, the problems correspond perfectly in order with the sections of the book. This makes it convenient for the students and easy to follow along.

Web. 11 Feb. 2013. <http://www.mathtv.com/videos_by_topic#>. This website, MathTV.com, gives excellent tutorials on solving any type of algebraic problem. It allows you to choose a topic, in this case, systems of equations, and watch a variety of problems being done on a white board, step by step. It’s important for students to have extra practice while at home, and if they were to forget how to go about solving a specific problem, this can be very useful in figuring it out. Not only does it offer a section on systems of equations, but shows examples involving every possible way to solve a system.

TeacherTube DeRitter, Paul. "Solving Systems of Equations Graphically TeacherTube DeRitter, Paul. "Solving Systems of Equations Graphically." TeacherTube. N.p., 2007. Web. 11 Feb. 2013. <http://teachertube.com/viewVideo.php?video_id=3079>. TeacherTube is also another excellent source of video tutorials. In mathematics, it is especially important for the students to visualize each problem, step by step, as these videos demonstrate. This particular one I’ve chosen goes over the concept of solving a system of equations using the graphing method. This method will be used often and this video gives a clear explanation of how to go about doing so.

Simultaneous Equations "Simultaneous Equations Simultaneous Equations "Simultaneous Equations." Fun Maths: High School Math. FunMaths, 2000-2011. Web. 11 Feb. 2013. <http://www.funmaths.com/worksheets/math_algebra_01.htm>. This worksheet is from the website FunMaths. The website contains an incredible amount of printable math worksheets pertaining to every subject and every grade level. This specific worksheet involves using the given axis to solve the given systems of linear equations. It is the perfect worksheet to go along with the unit on systems of equations, particularly relating to the graphing method.
