Flex and Flora 3 offers four competency-oriented workbooks, each dedicated to a specific area: reading, language exploration, correct writing, and text composition. The workbooks do not prescribe specific subject matter. They can be interconnected as well as used independently. The four workbooks are designed to be completed at the student's own pace. The individual learning process of the children is prioritized, and open teaching methods are supported. Within each workbook, the sequence of units serves as a suggestion. It 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 students. The introductory images facilitate discovery-based learning.
