In this lesson, students solve two-step word problems using all four operations. (For example, "Genevieve makes 43 bracelets. She gives 13 bracelets away as gifts and sells the rest for $4 each. How much money does Genevieve make in all?") In the process, they analyze each problem using tape diagrams and write equations with a letter representing the unknown. This lesson focuses largely on multiplication and division involving multiples of 10 so students can apply the strategies introduced in the previous two lessons.
