13 effective exercise units for students with reading and writing difficulties in regular classes, remedial courses, and workshop lessons! This volume stands out refreshingly from typical LRS exercise materials: The author offers a systematic morpheme training that should be part of the standard repertoire when working with word families. By using morphemes as the smallest meaningful units of language, the writing and reading training also becomes language training. The clearly structured division into prefixes, root morphemes, and suffixes significantly aids students in word analysis, allowing them to read and write the individual parts of words fluently and meaningfully. Each exercise unit addresses a specific source of error and includes texts, word collections, and fill-in-the-blank exercises for regular instruction, as well as additional resources for LRS courses and workshop lessons, such as flashcards, dice, and thinking fix discs.
