A minimalist text uses few words to great effect, as illustrations and text work together in an exploration of number concepts “one” and “two.” A mother bird with her filled nest and a girl walking alone are paired with the description “One bird, two eggs, / One girl, two legs.” The girl and a friend spend time together on the following pages, flying kites (“one cloud, two kites”) and sharing a snack (“one bun, two bites”). Their paths intersect with the mother bird, as “One swoops, two walk, / One sings, two talk.” The number order reverses for the remainder of the book, with the bird flying off (“Two wave, one flies”) and the friends sharing the feather gift she leaves behind (“Two share / one prize”). Charming collage art and a cozy size contribute to the intimate ambiance. (Ages 2–5)
