Freddy's first-grade class is learning all about penguins -- including the fact that some species are endangered. When Freddy suggests a penny drive to help save the penguins, everyone loves the idea. But Freddy can't find his penny jar! How will he save the penguins now?

First-grade and kindergarten teacher Abby Klein has been teaching for almost twenty years, and she brings her first-hand knowledge of children to this popular series. As well, she tailors each story and the language in it for new readers-using just the right words as well as the issues that are most important to children this age.

For extra fun, the word "fin" is hidden in every illustration, and children will have a good time playing the games in "Freddy's Fun Pages" at the end of the book. Attention shark lovers! Freddy Thresher is a first-grade expert on sharks, and each book features cool facts about sharks as an added bonus.
