Meister Cody - Test and Training Game for Dyscalculic children

Parents rarely notice early signs indicating their child is weak in math. However, a 2nd grade elementary school teacher spots them immediately. Here’s how. Give a 2nd grader two gummy bears. Then give him two more and ask „How many gummy bears do you have in your hand?“ A normal child will look up, think for a second, and say the answer four. He’s done the math in his head and doesn’t need to literally look at the gummy bears in his hand.


A child who is weak in math or suffers from dyscalculia will touch and count each gummy bear in his hand while saying, „One gummy bear, two gummy bears, three gummy bears, four gummy bears. There are four gummy bears“. This child always needs to physically touch and count the gummy bears one by one, use his fingers to count, and/or say out loud „one, two, three, four“.


Dyscalculia is a developmental disorder of arithmetical skills. Globally, 5-7% of school children suffer from dyscalculia and around 25% from math weakness. Unfortunately, dyscalculia isn’t as well known as its popular cousin, dyslexia, a reading and spelling disorder.


The Institute for Psychology at University of Münster and Kaasa health recognized the need for awareness, online testing and online training for dyscalculia. Together, we developed a scientifically-validated online test for 2nd- 4th graders that measures many parameters that cannot be detected using a conventional old school paper test. In addition to comparing accuracy, the CODY-Test focuses on individual response time, which is a very important aspect of the mathematical thinking process.


If dyscalculia or a math weakness is detected, a child can continue with the Meister Cody training, which has been scientifically proven to strongly increase learning success with addition and subtraction. The training is embedded in a fun and motivating game for children. Since math exercises are repetitive and boring, especially for children whose faces turn red in frustration when having to solve a math problem, the training is deliberately designed as a game, so that children are motivated to perform all the exercises on a regular basis. The training consists of approx. 25-30 minutes of daily tasks over a period of 6 weeks.


The combination of thrilling storytelling and science-based and -validated exercises is unique, innovative and effective at the same time. Following the training, a child will be re-tested, so that parents, teachers and therapists can follow a child’s progress.


Fighting dyscalculia also a strong economic impact. The Organisation for Economic Co-operation & Development (OECD) shows that small improvement in performance of math and science results in an increase in annual growth rates of GDP per capita of 0.87%. This means an extra $136 billion for the United States.


Join us in the global fight against dyscalculia. Meister Cody is already available in the German markets. In early 2014, we are localizing Meister Cody for the English-speaking markets and creating a global campaign to raise dyscalculia awareness. Help us ensure that all 2nd – 4th graders in the United States take the CODY-test.
