Information about the series publication: Learning together, but differentiated, with the new Math Friends. The teaching material Math Friends is part of the Friends network. It combines the practical experiences of teachers with new insights from primary school didactics. The revised edition implements the demands for inclusion in practice: In addition to the proven components of the teaching material, there are now two inclusion workbooks per grade level. These serve as both student book and workbook in one. With the expanded copying templates, there is an even greater range of exercises available for both students with special needs and high-achieving children. This makes differentiation a complete success. Structured and differentiated work: The tasks are clearly divided into three levels of differentiation. Review: Review tasks reinforce the material.
