Which Has More? is aligned to the Common Core State Standards for English/Language Arts, addressing Literacy.RI.K.6 and Literacy.L.K.1. Objects around the house that hold water are used to explain the concept of volume. Each spread features color photographs of two items holding water, such as a spoon and a cup, while accompanying text explains which object holds more water. This book should be paired with More or Less? (9781448886494) from the Rosen Common Core Readers Program to provide the alternative point of view on the same topic.
