Finding Irrelevant Sentences in Paragraphs

This is a worksheet that explains what irrelevant sentences are and then follows with an informative text about Sadako Sasaki (the Japanese girl who made 1,000 paper cranes) in which there is an irrelevant sentence, in each paragraph, that the students need to delete. There is no answer sheet as the answers should be obvious, if not students will be able to discuss among themselves.
