Book Reviews: Connors' tender story captures a young child’s vivid imagination, but it is also a teacher’s dream, incorporating facts about otters in “snapshots” on each page, augmented by detailed science facts and activities in the backmatter, with permission to print. Jones’ delightful, expressive, and smooth-edged digital illustrations are an apt match with the text and add humor while also sliding in still more otter facts. Deftly capitalizing on children’s predilection for imaginative play, this book neatly packs a solid informational punch. What child hasn’t wondered what it would be like to be an animal, able to hop, fly, or slither with ease? After a trip to an aquarium, Oliver decides he wants to be a sea otter. Oliver tries to copy sea otter behavior at meals, while playing, during a trip to the store, and at bath time. However, during the course of the day, Oliver discovers that he just doesn’t have the same adaptations. Being an otter isn’t easy for a human. What’s an otter—we mean, a boy—to do? This fictional story includes a 4-page For Creative Minds section in the back of the book and a 30-page cross-curricular Teaching Activity Guide online. Oliver’s Otter Phase 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.
