Learning goals: Learning Goals • Calculate the weight of an unknown object using a hanger diagram, and explain the solution method. (Lesson 2) • Calculate a value that is a solution to a linear equation in one variable. (Lesson 4, 5, 6) • Justify that each step used in solving a linear equation maintains equality. (Lesson 5) • Describe strategies for solving linear equations in one variable that have different features or structures. (Lesson 6) • Describe a linear equation as having “one solution," "no solutions," or "an infinite number of solutions," and solve equations in one variable with one solution. (Lesson 7) • Create an equation in one variable to represent a situation in which two conditions are equal. (Lesson 8) • Interpret the solution of an equation in one variable in context. (Lesson 8)
