Review Quotes: "Kids who find math rigid or daunting will be charmed by this messy, busy story of nine kittens frantically scurrying around, planning a welcome home party for Grandma... the vibrant, page-filling illustrations do an especially effective job of capturing the chaos... this effortless introduction to estimation makes a great read-aloud and works equally well for very young audiences or as reinforcement for slightly older students, who might also enjoy the additional estimation challenge hidden in the book." --Booklist
