Is your child struggling to learn math? These skills may include:

  • Addition, Subtraction, Multiplication and Division
  • Estimating: The ability to distinguish between amounts without counting
  • Subitizing: The ability to understand amounts of elements without counting
  • Number Representation: The ability to understand numbers as amounts in Arabic notation and as words
  • Ordinality: The ability to order numbers based on which is larger/smaller
  • Number range: The ability to place numbers correctly on a number line, develop a mental number line, and develop an understanding of a range of numbers
  • Math facts: The ability to quickly add a one-digit numbers with a one or two-digit result

Why might my child be struggling?

During childhood, certain regions of the brain develop to specialize in the processing of numbers and mathematical tasks. For children with weaknesses in mathematics, this natural development is delayed; sometimes, it largely fails to occur at all. Dybuster Calcularis offers a unique way of promoting essential learning and maturation processes in the brain. It combines modern findings from developmental psychology and neuroscience with tried-and-tested principles from the fields of information theory and computer science.

Custom-tailored Training

Dybuster Calcularis adapts its learning content to suit the capabilities and speed of each individual user. This means that each user's learning development is supported in exactly the areas where their difficulties lie. Personalized training modules offer learners a play-based way to overcome their arithmetic difficulties.

  • 48 different learning games improve the neuronal processing of numbers and the user's comprehension of a mental number line.
  • The software trains addition, subtraction, multiplication and division operations in a 0-1000 range.
  • The software lays essential foundations for the acquisition of more advanced mathematical skills.

Dybuster Calcularis really works:

Suggested training for Dybuster Calcularis consists of just three or four sessions per week that last 15-20 minutes each. Scientific studies show that targeted training with Dybuster Calcularis actually causes neuroplastic changes in the brain. After using Dybuster Calcularis, students1:

  • Increased their math skills
  • Solved more math problems
  • Made 35% fewer mathematical errors
  • Did significantly better when working with number line tasks
  • Had less math-related anxiety

Game-based learning

Dybuster Calcularis guides the child's learning. When necessary, it repeats certain content or exercises to ensure that learned material is consolidated and retained. Progress is displayed in the form of a friendly animation. As a reward, younger users can purchase animals for a virtual zoo, increasing their motivation and enhancing their enjoyment in learning.

  1. Scientific studies have shown that targeted training leads to neuroplastic changes in the brain in areas associated with the development of mathematical abilities (K. Kucian, 2011). After just six weeks of Calcularis training, learners can solve over 31% more math problems (T. Kaeser A. B.-M., 2012) and increased their subtractions skills from an average percentile rank of 12.9 to 29 percentiles (T. Kaeser, 2013). In a more recent study, learners showed significant improvements in number line tasks (L. Rauscher, 2016). In addition, Calcularis has been shown to reduce math anxiety (M. von Aster, 2015).
