Lehrer Lmpel: Digit Squares for iOS

By Claus Zinn $1.99

Developer's Description

Digit Squares is the new Teacher Lmpel educational app ! It supports primary school children to practise their skills in basic arithmetic: addition, subtraction, multiplication and division. 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 Lmpel 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 iOS8 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!
