This document provides lesson plans and materials for teaching students about multiplication and division using tape diagrams and word problems involving sharing quantities into groups. The lesson includes fluency practice in dividing by 2 and 3, an application problem about sharing $16 between 2 video games, and a concept development section where students use tape diagrams to model word problems involving dividing quantities into equal groups of 3 and writing corresponding division sentences. Students then generate their own word problems to match given division solutions.
