Das Übungsheft Mathematik - Kleines Einspluseins

The exercise book for the small one plus one is the ideal training tool to avoid counting arithmetic. Instead of simple memorization, the children are taught connections between addition tasks in order to apply them automatically. The exercise book offers various ways to improve and automate the transition between arithmetic problem and result. Calculation tricks such as - almost doubling - decompositions using the 5 - neighbouring tasks with the 10 - the step over the 10 help the children to get a feeling for the structure of the number range up to 20 and to internalise its characteristics. The understanding of the interrelationships is first brought close by means of various representations, so that later work can be automated on the symbolic level.
