Differentiated teaching with the new workbooks for support. Workbooks A and B for the Karibu reader are now available for weaker children as well. All pages are designed parallel to the regular workbooks, allowing both to be used side by side in the classroom. Potential stumbling blocks for weaker children are avoided, such as extended reading and writing of open syllables, the avoidance of similar sounds, as well as an optimized, reduced vocabulary with recurring images and words to prevent issues with naming. Word cards are included as an appendix for practicing terms and for numerous reading and writing exercises.
