レーラー・レンペル：割り算 — 筆算に自信を持ってマスターしよう

Lehrer Lämpel is an educational app that supports primary school children (usually 3rd or 4th. grade) to practise their long division skills. The app supports three common notation schemes to cover most of the notations used. The app gives immediate feedback, where incorrect steps are marked red and where correct steps are marked green. Learners can ask Lehrer Lämpel for help at any time! Help first removes an erroneously learner step; if there are no errors, a single step is performed towards the solution. Each step is explained ! The app offers long division for integer dividends and decimal dividends, and three levels of difficulty. Moreover, the app allows learners to define their own division tasks (say, to support homework exercises), and there are also worksheets, and a mechanism to generate an arbitrary number of randomised exercises (given the chosen difficulty level). The app supports English, French, Spanish, Italian, and German, as well as the most common notations for long division. It is easy to use. 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!
