Books in the Hide and Seek series provide an entertaining introduction to some of the words that tell us where things are. This book looks at On and Under, and features an animal character called Eddie the Elephant who is playing hide-and-seek. On each spread, Eddie is hiding using one of the two opposite words featured in the book s title, and the reader is asked to find him. The fun, cartoon-like design combined with the interactive hide-and-seek approach makes these books visually appealing for young readers and great to read aloud together."
