Guess What Is Growing Inside This Egg

  • Interest Level: Kindergarten - Grade 3
  • Reading Level: Grade 3

Crack, crack…animal babies are hatched all over the place. Can you figure out who’s who?

Watercolor and collage illustrations depict close-up scenes of an egg or eggs about to hatch. The text hints at what the eggs contain: “Hidden in a rock cave/ Deep beneath the ocean waves/ Their mother wraps her long arms around/ To keep these eggs safe and sound.” The observant young nature lover will find a visual clue of what animal the mother might be. The next spread provides the answer-in this case, it’s an octopus. The second spread also provides fascinating facts about the species.

The book features a number of species ranging from spiders to penguins to octopuses, and the back matter provides more information about the actual size of various eggs and how they develop.

Kirkus Reviews

“Posada again succeeds in bringing science to kids in this amazing treasure trove of information and beautiful collage art that’s wrapped up in a guessing game. . . Posada’s artwork lends texture and movement to the pages-readers can almost feel the downy softness of the duck’s breast and the rough scales on the baby alligators. This is wonderful for sharing on its own, but will be especially embraced by elementary educators.”

Publishers Weekly

“Posada’s paint and collage pictures are sumptuous in both texture and color; she beautifully evokes the furriness of a penguin’s belly and the mounded dirt and sticks of an alligator’s swampy nest. Even if the guessing may come easily, children will certainly learn a great deal about some youngsters of the animal kingdom.”
Publishers Weekly

The Bulletin of the Center for Children's Books

“Through the double pleasures of a rhymed riddle and a hidden-picture clue, children learn about half a dozen animals who begin life inside an egg shell. . . The full-bleed collages, crafted of painted and textured papers, can be enjoyed by individuals and small groups, and the information is right-sized for squirmy audiences with limited attention spans. . . This is a first choice for kindergarten classrooms or for the bookshelf of any child who appreciates nestling penguin chicks, snapping alligators, or parachuting spiderlings.”
