What do you do if you can't sleep? Count sheep! That's what the restless hero of this rollicking tale does. And when sheep don't work, he counts kangaroos by twos and monkeys by threes. But when he gets to bees by fours, the animals run amok! Then it's a countdown to dream time. With energetic, bright illustrations and rhythmic text, this is a great introduction to the idea of counting by sets, a precursor to multiplication.
