Flex and Flora 4 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 or used independently. The four workbooks are designed to be completed at the individual learning pace of the children, with a focus on their personal learning process and support for open teaching methods. Within each workbook, the sequence of units serves as a suggestion and can be modified, as each unit covers a self-contained 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 more advanced children. The introductory images facilitate discovery-based learning.
