DOUBLE PUPPY TROUBLE

A child who insists on having MORE of everything gets MORE than she can handle.

Demanding young Moxie Jo is delighted to discover that pushing the button on a stick she finds in the yard doubles anything she points to. Unfortunately, when she points to her puppy, Max, the button gets stuck—and in no time one dog has become two, then four, then eight, then….Readers familiar with the “Sorcerer’s Apprentice” or Tomie dePaola’s Strega Nona will know how this is going to go, and Masse obliges by filling up succeeding scenes with burgeoning hordes of cute yellow puppies enthusiastically making a shambles of the house. McKellar puts an arithmetical spin on the crisis—“The number of pups exponentially grew: / They each multiplied times a factor of 2!” When clumsy little brother Clark inadvertently intervenes, Moxie Jo is left wiser about her real needs (mostly). An appended section uses lemons to show how exponential doubling quickly leads to really big numbers. Stuart J. Murphy’s Double the Ducks (illustrated by Valeria Petrone, 2002) in the MathStart series explores doubling from a broader perspective and includes more backmatter to encourage further study, but this outing adds some messaging: Moxie Jo’s change of perspective may give children with sharing issues food for thought. She and her family are White; her friends are racially diverse. (This book was reviewed digitally.)

Doubles down on a basic math concept with a bit of character development.
