The grammar workbook for the INDIGO dictionary is ideal for working with learning groups that want to deepen their vocabulary and communication skills with knowledge of German grammar. Children and teenagers expand their vocabulary with words from the dictionary section of INDIGO, learn about the most important parts of speech, and practice using them in dialogue, while also deepening their understanding of different sentence types. The workbook can be used independently of grade level and age. The material can be used collaboratively in class, but the workbooks can also be utilized independently, with an answer key included. The vocabulary in the dictionary is based on the DaZ guidelines of all federal states.
