Series: Students with reading difficulties quickly become frustrated and give up when the reading material is too difficult, too long, and too boring. You can spare yourself and your students this frustration with the paperbacks from the K.L.A.R. series: A generally low amount of text, manageable reading sections, an easily understandable vocabulary, and everyday language help your students become confident readers. By addressing current topics from the students' world, they gain a desire to read and the courage to continue. The novel is therefore ideal for promoting reading in secondary education and can be used by teachers as school reading material in special needs schools, secondary schools, and comprehensive schools. Novel: Leander, Ben, Nino, and Jule - phone junkies and huge Minecraft fans - go on a class trip to the Eifel. There, the friends must learn to cope without network reception: they get lost.
