McGrath starts with a simple definition of a pattern and grows the concept progressively to include multiplication as well as odds and evens in her fourth installation of the McGrath Math series. Nihoff’s bold Photoshop illustrations appear to be Gummy Bear-inspired and are laid out against a stark white background sure to hold children’s attention. Although a mere 32 pages, teachers could potentially select a segment of the book to use with their classes for a lesson, depending upon the grade level. The book lends itself to interactivity, particularly since packages of plastic bears are available that students could manipulate. Ina climate with such emphasis on STEM (Science, Technology, Engineering, Math Curriculum), this is a strong choice for both school and public libraries.
