Working with data is a foundational concept t only for mathematics, but also for understanding the world around us. Readers will gain exposure to principles of measurement, such as measuring length and using it to perform operations, while other narratives introduce concepts of money and time. Bright visuals help make math t only concrete, but also fun. Discovering the diversity in a classroom provides the perfect context for students to learn how to create and use a bar graph. This volume meets CCSS Math Standard 2.MD.D.10.
