Lehrer Lämpel: Fractions Hack 1.4

Screenshots

Description

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!
