Experiences from teaching practice were the foundation for the selection, revision, and redesign of the topics in the new edition. The Pusteblume Workbooks 1 and 2 were specifically developed for teaching in mixed-age learning groups and for the use of differentiated learning materials in grade-level learning groups. The proven offering includes topics and content for two school years, all consistently designed both in terms of content and methodology for two performance levels. The selection of topics and the differentiated range of working methods ensure that children can acquire fundamental competencies largely independently, systematically, and creatively. The new Pusteblume Workbooks 1 and 2 consist of four-color informational and working materials. The pages are perforated, allowing them to be easily removed and distributed individually, and can be hole-punched for use in folders.
