Curtis’s celebration of language is also a vehicle to teach young children how behaviors can affect communication. Whether a little one needs privacy in the bathroom or must deal with a consequence for exploding bubble gum in class, learning to be responsible and considerate helps one to cooperate. Clear, example-filled definitions balanced with Cornell’s energetic drawings of active multiethnic children in familiar, everyday scenarios will have little ones developing their vocabulary with multisyllabic words like persevere and stupendous as they absorb the traditional golden rule of treating everyone with respect. Curtis concludes her theme with the one word all children understand, love, a little word with a huge significance. A gracefully appropriate addition to the duo’s superb collection.
