Kinder m\u00fcssen einen Text verstehen, relevante von irrelevanten Informationen unterscheiden, ein mathematisches Modell bilden und schlie\u00dflich rechnen. Viele scheitern dabei nicht an der Mathematik selbst, sondern bereits am Textverstehen oder an der Modellierung (Reusser 1997). Rechengeschichten ist eine App, die Kinder von Klasse 1 bis Klasse 6 und dar\u00fcber hinaus bei genau diesen Schritten KI-gest\u00fctzt begleitet: nicht durch Vorsagen von L\u00f6sungen, sondern durch strukturierte Impulse auf Basis erprobter L\u00f6sungsstrategien.<\/p>\n\n\n\n<figure class=\"wp-block-gallery has-nested-images columns-default is-cropped wp-block-gallery-1 is-layout-flex
