There are many different kinds of clouds all around us. Clouds come in diverse shapes and colors. Some clouds are fluffy and others are wispy. Some clouds float high in the sky and others sit low on the ground. Some clouds warn of storms and other clouds tell of fair weather. Compare and contrast the characteristics of different types of clouds through vibrant photographs. This nonfiction picture book with a cuddle factor includes a 4-page For Creative Minds section in the back of the book and a 17-page cross-curricular Teaching Activity Guide online. Clouds 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.
