Big Ideas: Real world situations can be represented by inequalities. Inequalities can be solved both algebraically and with visual models. This lesson builds on students' work with writing and solving two-step equations by transferring that prior knowledge to inequalities. The task asks students to consider three different video game subscription plans and choose the best deal for Eddie’s budget. Students justify their choice both algebraically and visually in a written recommendation to Eddie. This builds toward students' future work in fluently solving two-step inequalities and interpreting their solutions in grades 7 and 8. Vocabulary: visual model, algebraic solution Special Materials: none
