Algebra is a foundational concept in the study of mathematics, and readers will delight in learning the principles of operations and algebraic thinking in a relatable and engaging way. Topics such as adding and subtracting within 20, using algebraic principles to solve equations and word problems, and understanding the relationship between addition and subtraction will give beginning math students a firm grasp on basic math concepts. This volume, written to the Common Core State Standards for Mathematics, meets standard 1.OA.A.1 and uses a trip to the beach to make addition word problems fun for young readers. This book should be paired with Diego Goes to the Beach (9781477721124) from the InfoMax Math Readers Program to provide the alternative point of view on the same topic.
