Learning goals: Learning Goals • Calculate a value that is a solution to a linear equation with one variable, and explain the steps used to solve. (Lesson 5) • Determine a point that satisfies two relationships simultaneously, using tables or graphs. (Lesson 9) • Understand that solving a system of equations means finding values of the variables that make both equations true at the same time. (Lesson 11) • Connect the solution of an equation with variables on each side to the solution of a system of two linear equations. (Lesson 12) • Justify that a particular system of equations has no solutions using the structure of the equations. (Lesson 13) • Categorize systems of equations, including systems with infinitely many or no solutions, and calculate the solution for a system using a variety of strategies. (Lesson 13) • Calculate values that are solutions to a system of equations, and explain the solution method. (Lesson 13) • Calculate the solution to a system of equations in context, and present the solution method. (Lesson 14)
