An introductory primer for kids learning about the “M” in “STEAM” : Mathematics. Math is the basic foundation upon which most of the other areas of STEAM rely. If a child aspires to be a scientist or an engineer or an architect, they need to first understand math. Little Leonardo’s Fascinating World of Math introduces many mathematical concepts in a context showing their interconnectedness with so many of the things in our everyday lives. This new series of books featuring illustrations by popular artist Greg Paprocki is the perfect way to encourage your brilliant child’s interest in all facets of the educational STEAM curriculum: Science, Technology, Engineering, the Arts, and Mathematics. Your child will be enticed by the fun and surprising details revealed in Paprocki’s cool and colorful artwork on every page. K-Gr 2—Accurate and age-appropriate information fills each volume, which introduce kids to various disciplines and their overarching concepts. Science successfully introduces STEM-related fields, such as botany and physiology. In Arts, children are exposed to the various art mediums (oils, acrylics, computer aided design, clay, photography, dance, theater, etc.) as well as a brief history of art ranging from prehistoric cave drawings to laptop audio recording. Math conceptualizes a wide range of topics with increasing but manageable difficulty, including basic arithmetic, positive and negative integers, and basic equation writing. Each text includes a short biography of Leonardo da Vinci, a glossary, and a short listing of important individuals in the field. The illustrations, done in a Little Golden books—style, are less thoughtful. Science in particular lacks cultural sensitively, portraying characters with feather headbands and spears and stereotypical costumes.
