Flex and Flora 3 offers four competency-oriented workbooks, each dedicated to a specific area: writing correctly, examining language, writing texts, and reading. The workbooks do not prescribe specific subject matter. They can be interconnected as well as used independently. The four workbooks are completed at the individual learning pace of the children, prioritizing their personal learning process and supporting open teaching methods. Within each workbook, the sequence of units serves as a suggestion and can be altered, as each unit covers a complete topic. Each unit begins with an introductory page and a problem-oriented introductory image, which can be explored through learning discussions in the classroom or in small groups, as well as independently by advanced children. The introductory images facilitate discovery-based learning.
