The Mathematical Sciences Research Institute (MSRI) announced the 2018 winners today of the Mathical Book Prize, which recognizes outstanding fiction and literary nonfiction for youth ages 2-18. The committee chose Award Winners in the three youngest age categories in 2018 (Pre-K, Grades 1-2, Grades 3-5), and made Honor Book selections in all five age categories (also Grades 6-8, Grades 9-12). "We are trying to engage kids in the power and beauty of mathematics - power in that we want to give them confidence to consider and solve arithmetic, spatial, logical, structural, algebraic problems; beauty in that math can be employed to better understand and appreciate the wonders of nature and also human artistic expression, for example in fine art and music," said Roger Strauch, MSRI board chair and chair of The Roda Group, a Berkeley venture capital firm. A committee of PreK-12 teachers, librarians, mathematicians, early childhood experts, and others selects the prize,
