Nine kittens go on an exciting boating adventure that’s a (funny) catastrophe in this playful picture book that demonstrates the key math concept of patterns. A crew of hungry kittens and their captain head to the lake to catch some dinner, but the fish have surprises in store for them. Even before the cats encounter the fish, they run into trouble. What happens when confused kitties paddle every which way? Or when they all lean in the same direction? A pattern is needed to avoid a catastrophe! Patterns are the foundation on which math is built. Using strong rhythm, clever wordplay, and countable characters, CATastrophe! is a fun read-aloud that also shows what patterns can do. Helpful backmatter will deepen readers’ understanding and challenge them to find more patterns in this book and in our world. There’s also much to find in the illustrations—including a dragonfly and worm that each appear twenty times.
