Accessible narratives make learning the skills of composing and decomposing numbers fun for beginning math students. Simple text allows readers to explore these crucial concepts on their own. Colorful images help students visualize place value in a way that is both educational and engaging. Composing numbers is made simple for students by relating this math concept to building with blocks. Written to reflect the Common Core State Standards for Mathematics, this volume directly addresses standard K.NBT.A.1. This book should be paired with Building with Blocks (9781477719619) from the InfoMax Math Readers Program to provide the alternative point of view on the same topic.
