Welcome to the Roller Derby Showdown! On the stage today are the Thrashin' Than and the Thunder Then. You know the grammar rules: use 'than' to compare things, and 'then' to talk about time or what happens next. There are eleven rounds in the challenge. In each round, read the sentence and decide which one fits best: than or then. Tally the scores and see which team wins the Roller Derby Showdown!
