Animal Count

Sliding panels add fun to the concept of 1, 2, 3 in Animal Count by Salina Yoon. The sturdy corrugated pages feature windows that ease across the picture to reveal hidden animals, as the poem counts to 10: ""I see three turtles on the farm./ Add one more and you get four."" Opposite the sliding panel, all the cheery, pastel-hued animals from previous pages congregate. (Aug.) .
