Count the Monkeys by Mac Barnett

Hey kids! Time to count the monkeys!

It's fun.  It's easy.  All you have to do is turn the page . . .

and

COUNT THE MONKEYS!

And so starts a counting adventure.  And one of my new favorite counting books. 
Each turn of the page introduces an ever-increasing number of animals or people who have chased away the monkeys.  Children are asked to participate in the reading by scaring away the animals, closing their eyes, or humming a happy tune.

A definite must-read for any child learning, or reviewing, their numbers!
