Las ranas de la madera (wood frogs) [PDF ebook] 

It’s a cool fall day in a forest. A tiny brown wood frog hops under a log and covers itself with leaves. Soon, the sky turns gray and snow begins to fall. When the snow touches the frog, its body freezes solid! The frog will spend the winter hibernating in this frozen state. In this dramatic and colorful book, beginning readers will learn all about what wood frogs do in winter and the amazing ways they survive—including freezing solid in winter and then thawing when the weather gets warmer! Each 24-page book features controlled text with age-appropriate vocabulary and simple sentence construction. The lively text, colorful design, and exquisite photos are sure to delight and engage emergent readers.
