Learning goals: Learning Goals • Solve equations of the form `px+q=r` and `p(x+q)=r` that involve positive and negative numbers, and explain the strategy. (Lesson 7) • Expand and factor expressions that include positive and negative coefficients. (Lesson 8) • Solve equations that involve expanding an expression. (Lesson 8) • Write equivalent expressions with fewer terms by expanding and adding terms. (Lesson 10) • Solve equations that involve adding and expanding expressions. (Lesson 11) • Draw and label a graph on the number line that represents an inequality. (Lesson 13) • Determine and graph the solutions to an inequality with only positive numbers. (Lesson 14) • Write an inequality to represent a context. (Lesson 15) • Solve an inequality in context using its corresponding equation. (Lesson 15) • Use substitution to determine the direction of an inequality when solving. (Lesson 16) • Write and solve an inequality to answer a question about a situation with a constraint. (Lesson 17) Materials Allow students to use calculators to ensure inclusive participation in this activity.
