Karibu - the primer with the proven syllable strategy (based on Carola Reuter-Liehr) is the ideal teaching material for differentiated beginner instruction. The action-oriented methods and clear language structures provide a solid foundation for working in heterogeneous classes. From language support to challenging high-performing children - Kari and Bu help all children find their own way through the unfamiliar world of literacy acquisition. Reading is offered at three progressive levels, with new seasonal pages for a broader reading selection, references to the workbook, opportunities for cooperative learning, and "I-can-do-this-already" pages for assessing learning progress. The interactive primer is a consumable material: children write directly in the primer, draw syllable arcs, highlight vowels, and more.
