Alexa and the other children at her escuela in Costa Rica have a special project: they are raising American Crocodiles. She names her croc Jefe, which means "boss," because he seems to be in charge of all the other babies. Alexa brings him chicken and frogs to eat, and writes about his progress in her diary. Soon, her little hatchling is as big as a loaf of bread. He has grown into a juvenile and it is time for Alexa to say goodbye and for Jefe to return to the wild. This work of narrative nonfiction includes a 4-page For Creative Minds section in the back of the book and a 20-page cross-curricular Teaching Activity Guide online. After A While Crocodile is vetted by experts and designed to encourage parental engagement. Its extensive back matter helps teachers with time-saving lesson ideas, provides extensions for science, math, and social studies units, and uses inquiry-based learning to help build critical thinking skills in young readers. The Spanish translation supports ELL and dual-language programs. The interactive ebook reads aloud in both English and Spanish with word highlighting and audio speed control to promote oral language skills, fluency, pronunciation, text engagement, and reading comprehension. Tap animals and other things that make noise to hear their sounds.
