The Student Text provides a lot of opportunities to review concepts and skills taught in previous lessons, allowing students to reinforce their understanding and make connections between different topics in Algebra. However, this lesson may be modified in order contain more practice on solving linear inequalities and fewer problems. “analyze” Students will not be assessed on graphing inequalities (in 1 variable) on a number line.
