Work with Money

Working with data is a foundational concept not 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 not only concrete, but also fun. Readers learn to solve word problems involving money as they see how much fun it is to start a business in their neighborhood. This volume meets CCSS Math Standard 2.MD.C.8.
