Common Core Algebra 1, Unit 3: Systems of Equations

Collector: Ann V.

The five lessons in the third unit of the Common Core Flipped Math series focus on Systems of Equations. Each lesson comes with videos that teach the concepts, worksheets, practice packets, and corrective assignments. The unit begins with young mathematicians learning about the standard form equation of a line. They see how to determine whether ordered pairs represent a solution to a linear equation and how to rewrite the equation in slope-intercept form. The second lesson focuses on systems of inequalities. Scholars learn how to identify solutions to inequality and how to graph inequalities. They then see how to graph systems of linear inequalities. Next, viewers learn how to graph systems of linear equations to determine whether they have one solution, no solution, or many solutions. They then see the narrator working through several examples of solving systems of equations using substitution. The fifth installment explores the elimination method for solving systems of linear equations. For the unit review, learners determine whether points are solutions to linear equations, graph systems of equations and inequalities, and solve linear equations using the substitution and elimination methods.
