And Two Boys Booed — Judith Viorst

On the day of the talent show, a boy is ready to sing his song, and he isn't one bit scared because he has practiced a billion times, plus he's wearing his lucky blue boots and his pants with all ten pockets. But as all of the other kids perform before him, he gets more and more nervous. How the boy overcomes his fear of performing in front of the class makes a charming and funny read-aloud, complete with ten novelty flaps to lift.
