KBruch

KBruch separates fraction arithmetic from comparison, conversion, factorisation and percentage exercises. That makes it possible to practise the step causing difficulty rather than repeat an entire mixed worksheet. Ask a learner to write the reasoning on paper before entering the answer. The programme checks input and gives feedback, while an adult can use a visual model to explain a mistake.
