A clever board book shows the stages of building a house, with each page spread labeling four different tools and asking to whom they belong. “Keep all rooms dry in rain or snow. Whose tools are those? Do you know?” is the question on a layout that features a utility knife, nail gun, snips, and ladder. A foldout page reveals the answer (“the Roofer’s!”) and shows a worker or workers on the job using the tools. The workers include both men and women and are culturally diverse in a board book that is a wonderful vocabulary builder and discussion starter, in addition to its obvious child-appeal. (Ages 2–4)
