## Grade 1 Mathematics Module 3, Topic D

Topic D closes the module as students organize, represent, and interpret personally relevant data in Lesson 10 (1.MD.4). As students work as a class to collect, sort, and organize data into a graph, they find great purpose and excitement in data. They begin to answer, and then ask questions about, the number of data points in a given category, and in two categories. For Lesson 11, students take a more independent role in the collecting, sorting, organizing, and representing phases involved in graphing. They work on their own to ask and answer questions about the data set, which prepares them for the comparison work of the last two lessons. In Lesson 12, students interpret information presented in the graphs by exploring compare with difference unknown problems. They begin with visualizing these problems in their easily accessible “equalizing” contexts, by answering questions such as, “How many more students would Category A need to have the same amount as Category B?” Students use their understanding of comparing lengths from Topics A, B, and C to now compare the responses in three categories.
