Information about the series: Fredo, the curious coati, guides students through mathematics with tips and stimulating questions. Teach with differentiation using Fredo. The exercises are available at three levels: essential tasks for all students, simple tasks for children who need preparatory exercises, and challenging tasks for more advanced children. Each child works at their individual level on the open tasks in the learning diary. Teach with structure using Fredo. The clearly structured pages always focus on a specific topic or context. Less is more: thanks to the recurring exercise formats, there is less need for explanations, allowing more time for the children. Language corners ensure the necessary mathematical terms, easily recognizable by the little dog. Workbook - optionally with interactive exercises. The workbook is visually engaging.
