Goodnight, Numbers

Actor and author McKellar (Math Doesn’t Suck) brings her enthusiasm for mathematics to a younger crowd in this gentle and well-executed counting book. As the book proceeds from one to 10, cherubic toddlers of various ethnicities interact with their parents and surroundings: “Goodnight, four paws./ Goodnight, kitty cat./ Goodnight, four froggies/ on the bathroom mat,” writes McKellar as one father runs a bubble bath for his daughter. Padrón’s (Little Fox, Lost) cozy watercolor vignettes are stuffed with objects to count, providing bountiful opportunities to explore each number in depth, and closing notes offers tips for adults hoping to encourage kids’ interest in math. Ages 2–5. Author’s agent: Laura Nolan, Kuhn Projects. Illustrator’s agent: Minju Chang, Bookstop Literary. (Mar.)
