Algebraic skills are important building blocks for competency in math. Critical concepts dealing with operations and simple algebraic methods are explored, including addition and subtraction techniques, simple word problems, and decomposing numbers. Helpful images engage readers, and accessible text makes each skill easy for them to understand. Dogs and cats at a kennel help readers learn to decompose numbers into pairs. Written to reflect the Common Core State Standards for Mathematics, this title directly addresses standard K.OA.A.3. This book should be paired with Books at the Library (9781477716298) from the Rosen Math Readers Program to provide the alternative point of view on the same topic.
