Lesson objective: Organize and represent data into categories.

Students bring prior knowledge of classifying objects from K.MD.B.3. This prior knowledge is extended to organizing and representing data as students are given a set of objects that can be organized into categories and displayed in visual ways that represent the data. A conceptual challenge students may encounter is believing that there is only one way to organize data into categories when there may be multiple options.

The concept is developed through work with organizing and representing a real-life data set, which allows students to model the data in a picture or the beginnings of a picture graph.

This work helps students deepen their understanding of numbers because the number of data points in each category can be counted separately or can be combined into a larger group.

Students engage in Mathematical Practice 4 (Model with mathematics) as they create a picture of their data organized to model the planting of seeds in a garden.
