Information about the series edition: Differentiation: individual learning. With Einstern, students work independently and at their own pace. While some children have completed all tasks, others still need time and assistance. Einstern makes this possible, for example, with the principle of action-image-symbolism. This provides teachers with the opportunity to support individual children specifically. Thematic and workbooks Volume 1: All thematic workbooks are consumable materials. From Volume 2 onwards, you have the choice between consumable and loan materials. There are separate workbooks available for the loan materials. Even more consistent in use: structured representations against counting calculations, prompts for collaborative action and discussion, actively exploratory learning alongside automated practice, consideration of all educational standards, and a meaningful use of repetitions.
