PreS-Gr 4— Identifying patterns in nature is the topic of this comprehensive picture book. Perron uses simple rhyming text contrasted with more scientific information, including specific nomenclature, to help young readers identify patterns in different places in nature. Beginning with definitions, the author takes readers on a guided tour of the natural world, including plants, landforms, coral, waves, and rocks to demonstrate the breadth of patterns available to the observant person. Vividly colored photographs with both broad, encompassing views and detailed close-ups are enthralling. These help readers connect with the text and with their own environments. The rhyming text is brief and interesting enough to keep the youngest readers engaged; older readers will love learning about basalt columns, barchan dunes, venation, and why there are ripples in the sand under the water. VERDICT With content that will appeal to a wide range of readers, this beautiful book about patterns is excellent choice for elementary libraries.— Debbie Tanner
