“Everybody loves to shout. So if you know it, shout it out!” A clever—and noisy!—concept book encourages young children to share what they know as numbers from 1 to 10, the letters of the alphabet, colors, animals, and various vehicles are featured in turn. The vibrant illustrations include a group of diverse, energetic children with wide open mouths. Items represented by pictures, such as individual animals and types of vehicles, are labeled with their corresponding words. A visual subplot shows a little mouse who occasionally pipes up with a quiet comment (distinguished by small type). The penultimate page spread gives Mouse a chance to show his stuff, however, as he shouts out everything one more time in a spirited book for storytimes or lap time (but probably not bedtime). (Ages 2–5)
