The unique feature: each problem is only spoken aloud and doesn't appear as numbers on the screen. Just like in math dictation at school, when the teacher dictates a mental math problem, your child hears the problem read to them, remembers the numbers, and solves the problem mentally.

WHY LISTENING IS MORE EFFECTIVE THAN READING

Many children read numbers from the screen and simply type in the answer. True mental math requires this step. When a problem is only read aloud, your child has to listen, memorize the numbers, and work through the calculation process in their head. This is precisely the skill children need in elementary school and in everyday life.

WHAT YOUR CHILD PRACTICES

• The multiplication tables (1x1 and 1x2), step by step

• All four basic arithmetic operations: addition, subtraction, multiplication, and division

• Addition, subtraction, times, and division within the number range up to 10,000

• Calculation strategies from the Bavarian curriculum (LehrplanPLUS): doubling, auxiliary operations, core operations, place value calculations, inverse operations, and division with remainder

This way, the multiplication tables aren't simply memorized, but understood. The multiplication tables end up in their head, not on paper. Your child learns, for example, how to solve a difficult problem using a simple auxiliary operation.

SEVEN LEVELS, AROUND 1,000 PROBLEMS

The app grows with your child. Level 1 is suitable for the end of first grade, while the subsequent levels accompany second, third, and fourth grades. For each problem, a quick hint on the calculation strategy is available via "Help," and the solution can be accessed at the touch of a button. This way, your child can practice math for a few minutes every day and learn arithmetic step by step.

MATES THAT FIT SCHOOL

Tasks and strategies are aligned with the elementary school curriculum. Whether it's multiplication tables, the basics, or calculations with larger numbers: your child practices math as it's presented in class and will approach the next math lesson with more confidence.

FOR PARENTS AND SIBLINGS

• Multiple child profiles, ideal for siblings
• Parent area with progress charts
