Often, suitable, quickly deployable exercises that can be used in heterogeneous learning groups without much preparation are missing from the teaching topic. This collection provides a solution! For each topic, you receive three pages: The first page presents the respective fundamental mathematical relationships. This page is suitable as a handout for a slide as well as a basis for developing a blackboard illustration. The second template contains varied, playfully designed exercises at increasing levels of difficulty. The third page includes the solutions; it can also be used as a handout and given to students for self-checking. The exercises address the content of grade 2, and the task formats have been chosen according to the educational standards in the subject of mathematics. Thanks to the clear and organized design, the materials are easy to understand.
