Play ball! In this book, beginning readers are introduced to the baseball field and its bases, rules of play, and baseball equipment and gear. High-frequency words and repetitive sentence patterns work together with strong visual references to support the earliest readers and create a fun first nonfiction reading experience. Baseball includes Tools for Teachers and Caregivers, a Let's Review! question and image, and introductory nonfiction features such as labels, a table of contents, words to know, and an index. Baseball is part of Jump!'s Let's Play Sports! series.
