Description
The learner is given a square of nine fields, with some fields already filled with some digits. Each row and column points to its "result number". The task is to fill-out the empty fields ! There are three simple rules:
- all digits from 1-9 must be used to fill the 9 fields.
- no digit can be used twice.
- all sums and products must be correct.
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 the choice between PLUS and PRODUCT puzzles; the first option trains learners' addition and subtraction skills; the second option trains learners' skills in multiplication and division.
The app supports a large number of randomised exercises (all combinations to place the digits from 0-9 on a playground of 9 fields), and three levels of difficulty.
Optionally, a voice-over is available (male and female voice in English and French; female voice for German) that reads-aloud all help.
Supports English, French and German.
Available on the iPad, for iOS9 or later.
The app is ad-free. No data is being collected. No web access is required.
Please consider leaving a review. This helps a lot. Thanks!
