Actor-author McKellar, who has a mathematics degree, uses catchy visuals to teach kids and parents multiplication and division in a way that's more entertaining than memorizing times tables. Colorful illustrations and appealing cartoon graphics, stories, and rhymes explain multidigit multiplication and long division. A cartoon McKellar and her cartoon animal companions, Mr. Mouse and Ms. Squirrel, time travel to different time periods and places, learning multiplication and division concepts (ancient Rome highlights rows versus columns, while chocolate bars illustrate arrays of squares to show area). Each chapter includes math games with answers at the end of the book. Comics sidebars have fun facts, and Quick Notes sections offer brief explanations of concepts or definitions. A new math translation guide at the end is helpful for parents—it includes arrays, area models, decomposing factors and decomposing multiplication, the box (or grid or window) method, a place-value chart for division, partial products, and fact families. The text and fun visuals make the book a useful way to teach mathematics to kids and parents alike. Grades 3-5. Copyright 2020 Booklist Reviews.
