This lesson plan teaches 7th grade students about stem and leaf diagrams. The lesson will have students organize various data sets into stem and leaf diagrams, including birth months of classmates, earthquake magnitudes, blood pressure readings, and numbers of students who experienced bullying. The lesson aims to help students understand what stem and leaf diagrams are, how they are constructed, and how they can be used to organize data for easier interpretation. The lesson will conclude by having students construct and interpret their own stem and leaf diagrams.
