"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. The text and fun visuals make the book a useful way to teach mathematics to kids and parents alike." —Booklist
