Working with data is a foundational concept not only for mathematics, but for also understanding the world around us. Readers will gain exposure to principles of measurement, such as perimeter and area, and will also learn how to apply them to math operations. Engaging visuals help make math not only concrete, but also fun. Butterflies and moths come in a whole host of sizes. Readers will learn how to measure them to the nearest fourth or half of an inch. This volume meets CCSS Math Standard 3.MD.B.4.
