Basic Arithmetic on the iPad.
Our Lehrer Lämpel Apps offer multiple levels of difficulty. There are exercices that are rather easy, medium ones, and also challenging exercices.
Apps give direct feedback. If configured accordingly, learners see immediately whether their steps is correct or incorrect.
Our Lehrer Lämpel App for fractions is capable of identifying typical errors, and generating appropriate remedial feedback.
Our Lehrer Lämpel Apps never give away the entire solution, but lead learners step-by-step towards the solutions - by giving context-sensitive hints.
Our Lehrer Lämpel Apps have no fixed pool of exercises. In fact, there are unlimited exercises! For basic arithmetic, there are also predefined work-sheets. Or define your own math problem!
Our Apps NumberPyramids and NumberWheels allow learners to train their math skills under time pressure. Can you solve a number wheel in record time?
One of the first algorithm, pupils learn at school. The App allows learners to deal with 5-digit numbers.
Supports two basic subtraction algorithms: the decomposition method as well as the equals addition method.
Worksheets, self-defined or randomized exercises. Step-by-step help.
