Up! Up! Up!: Skyscraper

PreS-Gr 2–From the concrete foundation to the final spire, this nonfiction picture book shows young audiences the basics of building the exterior of a skyscraper. Each spread depicts one step in the process, from digging the initial trench and pit to installing rebar and concrete to building floors skyward with beams and glass. A small inset box included on each spread provides a cutaway view of the skyscraper's gradual progress. Two separate blocks of text describe each stage of construction, one with a simple rhyme for reading aloud and the other providing a sentence or two of descriptive prose. O'Rourke's digital illustrations have a charming cartoon quality yet successfully depict tools and machines with detail and accuracy. Additionally, a green wall along the top of the construction site acts as a reference point as the building progresses, and color-coding between the inset box and the larger illustration makes it easy to pick out each of the key elements, from gray concrete piles to orange beams. Labels abound for those curious about the different parts of a cement mixer or the names of the various large vehicles digging, drilling, and hauling. The diverse cast of male and female construction workers all wear hard hats, safety goggles, and vests, and safety netting and harnesses are frequently pictured.
