Big Idea: Inverse operations can be used to solve inequalities algebraically in the same way they are used to solve equations. This lesson builds on students' knowledge of writing and solving two-step equations by applying it to inequalities with positive coefficients. The task asks students to write and solve an inequality that will help them determine the length of a dog run. They must then find three different dimensions of the dog run that meet the given criteria and write a proposal to their parents, suggesting that they build one of them. This builds toward students' future work in fluently solving two-step inequalities in grades 7 and 8. Vocabulary: inverse operations, inequality, equations Special Materials: none
