To complement Book 1 and Book 2, Konfetti offers two workbooks that can be used with the corresponding card sets: Investigating Spelling and Language Use, as well as Reading and Writing Texts. This follows the well-known course principle: Children develop writing and reading strategies at their own pace. The workbook Investigating Spelling and Language Use 1/2 has the same structure as Reading and Writing Texts 1/2. It includes a clearly structured learning planner and tools for strategy-based learning. This workbook comes with a vocabulary notebook, an ABC notebook, and a toolbox workbook. These supplements are also available as a set of ten for reordering.
