The Flex and Flora Reading Book 1/2 contains an introductory story that can be read progressively according to the letter booklets 1, 2, and 3. Following this, theme-oriented units with reading materials are offered for all children working with the booklets of grades 1 and 2, allowing them to read and explore. The triple differentiation, the reliable structure of the units, and the methodological appendix enable children to engage with texts independently at their own learning pace. The Flex and Flora Reading Book - the thematic units. The core of the Flex and Flora Reading Books consists of eight thematic units that provide extensive and differentiated reading material for the respective grade levels. To help children navigate confidently, all eight thematic units follow the same structure: the introductory double pages provide word and image materials for all children.
