Skills dealing with counting and cardinality provide essential foundations for beginning math students. Readers learn important topics, such as counting from 1 to 10, comparing numbers, answering "how many?" questions, counting by 10s, and writing numbers. Each topic is explained in detail using accessible text and colorful images to help readers independently explore these core math concepts. A collection of marbles is used to help readers count by 10s to 100. Aligned to the Common Core State Standards for Mathematics, this book addresses standard K.CC.A.1. This book should be paired with "Counting Flowers Is Fun" (9781477716595) from the Rosen Math Readers Program to provide the alternative point of view on the same topic.
