Collection of Maths games created by INSERM-CEA Cognitive Neuroimaging Unit with dyscalculia in mind:
"The Number Race is primarily designed for children aged 4 to 8.
Children who are making their first steps with numbers will learn the basic concepts of number and arithmetic. Older children, who are already familiar with numbers, will build their fluency in arithmetic and in mapping numbers to quantities (number sense).
The game is especially designed to address mathematical learning disabilities (dyscalculia), by strengthening the brain circuits for representing and manipulating numbers."
