With intelligent error diagnosis and help! Lehrer Lämpel is an educational app that supports school children (usually 5rd grade) to practise their fraction addition and subtraction skills. The app is built-upon a state-of-the-art algorithm for diagnosing all student action and for providing targeted, situation-adaptive help. Pupils can ask Lehrer Lämpel for help at any time. A hint mechanism guides learners towards the next step, or points them to the source of the error. The app offers fractions with numbers that involve 1 or 2 digits. Lehrer Laempel supports two methods for combining fractions: "the least common multiple", or "any multiple". Optionally, a voice-over is available (male and female voice in English and French; female voice for German) that reads-aloud all help. Supports self-defined fraction addition/subtraction tasks and there is a work-sheet, and randomised exercises. Supports English, French and German. Available on the iPad, for iOS9 or later. The app is ad-free. No data is being collected. Please consider leaving a review. This helps a lot. Thanks!
