for Llaman a la puerta by Pat Hutchins and Aida E. Marcuse
From the Publisher
Hutchins' mouthwatering story about Marna's freshly baked cookies will certainly appeal to Spanish speakers. The spirited illustrations, filled with cookies, interracial children, toys, & a cat, add a buoyant tone to this picture book that also teaches a thing or two about addition & subtraction in an appetizing manner
