Algebra I is a class taken by 9th and 10th grade students as a requirement towards graduation. Because the depth of knowledge required for the course, some of the9th grade students may be required to take Foundations to Algebra in order to acquire some of the necessary skills needed to master the objectives in Algebra I. therefore by the end of their sophomore year, all students will have taken Algebra I. This unit is based upon the understanding of linear equations in algebra, a unit that is very rigorous. In this unit a student will learn how to create, solve and graph linear functions. Word problems will be used as a tool for students to learn how to create equations between quantities. While exploring this unit, students will also …show more content…
After creating the equations for these word problems, the student will commence to justifying the steps in solving for the solutions. The relationship of the equations will be shown by graphing the lines to demonstrate the point of intersection of the equations which were created. The TI-84 by Texas Instruments, a scientific calculator, may be used as a tool for this exercise. A tutorial on the different functions of this instrument will be given by the educator to help enhance the student’s skills needed to master graphing. The students will now be asked to push the button(y=) on the calculator to begin entering the equations into the calculator. After the equations have been carefully entered into the …show more content…
Systems of equations may involve two to three different equations that may have the same solution. A student may utilize three different approaches or methods to solving a system of equations: elimination, substitution, or graphing. Students will learn how to use the process of elimination by finding a common factor in the group of equations given or multiplying a number with one of the terms in the equation with its opposite, therefore eliminating one of the terms and solving for the variable that has not been eliminated. The next method a student may use to solve the system of equation is substitution. By using this method a student will place one of the equations in slope intercept form(y=mx+b) and solve for (y). After the (y) value has been obtained, the student will then substitute the value for (y) in the other equation and solve for (x), therefor giving you your (x) and (y) values. The last and final method to solving a system of equation is graphing. Students will then be asked to recall prior knowledge of how to put equations in the calculator and graph the line, and find the point of
