Exploring plane figures

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 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. In this book, readers will recognize plane figures in a school setting and learn how to find their area. This volume meets CCSS Math Standard 3.MD.C.5a&b.
