In this lesson, students learn how to write word statements as variable expressions and equations, then solve and check them. Through a series of word problems, they are guided on how to set up equations and solve for variables, including how to check their work using common sense. By the end of the lesson, students should be comfortable solving algebraic word problems and be able to confidently apply these skills to a range of other problems.
