Ramona's big day has finally arrived! This is the day she starts kindergarten and it's even better than she could have imagined. Her teacher promises her a present. She learns a great new song about "the dawnzer lee light." There's show and tell, learning to write her name, playing Gray Duck, and marching with the old kids in the Halloween Parade. But, she certainly proves she can be the peskiest kindergartender ever to Beezus' friend Henry Huggins and bossy Susan with the boing-boing curls. Things get out of hand when Ramona feels her teacher doesn't love her anymore and it's almost enough to make her the world's first kindergartener drop-out.
