Inhalt: The 'CATastrophe! cats' are back, this time causing even more chaos! Nine kitties are purring with excitement for Grandma Cat's upcoming visit. They're going to throw her a party with cake, decorations, and a special gift. But when frantically cleaning cats misjudge how many toys they can hide in a closet, catastrophe looms…. Author Ann Marie Stephens draws upon more than 30 years of teaching experience to ensure that readers absorb math while having fun in the adventure-filled 'CATastrophe Tale' series. And Jenn Harney's hilarious and energetic illustrations capture the antics of these enthusiastic kittens. Each book in the 'CATastrophe Tale' series includes helpful back matter, which shows readers that, just like the kittens, they use mathematical skills in their everyday lives. Additional titles in the series include 'CATastrophe!: A Story of Patterns' and 'CATawampus!: A Story of Shapes'.
