Calcularis learning games: helping to solve dyscalculia
Judging quantities, performing simple arithmetic, picturing numbers on a number line: all of these tasks can cause severe frustration to someone with dyscalculia. Math problems that pose no difficulty to their peers, can seem incomprehensible to dyscalculic children.
An inability to deal with numbers can leave dyscalculics with deep feelings of anxiety and inferiority when faced with anything math-related, such as counting out change or remembering the multiplication tables.
When children with dyscalculia play the Dybuster Calcularis learning games, the software gradually helps the brain to develop new learning channels and to automate mathematical processes. User studies have shown these games to be very effective: students using the software over a period of three months improved their addition skills by 30% and subtraction skills by 40%.
The games are designed to develop both numerical understanding and arithmetic operations. Students practice numbers as quantities, number words, Arabic numerals and positions on a number ray. Children progress from comparing amounts, to adding and subtracting with colored blocks, to multiplying and dividing. As their skills increase, dyscalculics also gain confidence in their own number abilities.
The results of the users studies involving Dybuster Calcularis were published in the following peer-reviewed publications:

But our favorite reviews come from the parents, teachers, and students who use our software:
“As a mother, I am extremely impressed by Dybuster.” – Katharina, mother
“I like the fact that I can use Dybuster on my computer at home instead of having to visit a therapist.” – Jonathan, 12 years oldPosted by Rebekkah Laeuchli | 1 comments
