Tom’s Field Trip is aligned to the Common Core State Standards for English/Language Arts, addressing Literacy.RI.K.2 and Literacy.L.K.4. Readers are introduced to the very basic concepts of comparative words, adjectives, and adverbs through a trip to the zoo. Color photographs depict animals and objects at the zoo, while compare and contrast text builds vocabulary for the reader within one to three sentences. Bears aren’t just playing; they’re playful. Giraffes aren’t just tall; they’re taller than most other animals. A chart in the back of the book lists root words and their variations to reinforce new knowledge. This book should be paired with Time for a Field Trip (9781448887521) from the Rosen Common Core Readers Program to provide the alternative point of view on the same topic.
