Solving Systems of Equations Without a Graph
Lesson 7 of 13
Objective: Students will be able to solve a system of equations algebraically by substituting one equation into the other in order to have an equation in one variable. Students will become fluent in this algebraic technique and will conceptually understand the reasoning behind using the substitution technique.
Choose one problem from your independent practice and write out in words why you solved it the way you did. List the steps and a reason for each step" If some students in your class struggle with writing they can explain their description to you. This task will determine which students are understanding the substitution method and which students have only memorized the procedure.
