In this lesson, students solve one and two-step word problems involving multiplication and division. (For example, "Asmir buys 8 boxes of 9 candles for his dad's birthday. After putting some candles on the cake, there are 28 candles left. How many candles does Asmir use?") 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 units of 8 in order to build fluency with those facts.
