The training booklet can be ideally used as a homework notebook or for additional differentiation. It consists of 64 pages and follows the structure of the math wheel. The tasks can be easily integrated into the children's respective math plans. The booklets can be worked on independently, as only task formats that have already been introduced in the corresponding workbook are used. The tasks are either completed directly in the training booklet or in the calculation notebook. Before each task, there is a space for the children to note when they received the task as homework.
