A condition that affects the ability to acquire arithmetical skills. Dyscalculic learners may have difficulty understanding simple number concepts, grasping numbers, problems learning number facts and procedures.
The earliest appearance of dyscalculia is typically a deficit in the ability to know, from a brief glance and without counting, how many objects there are in a small group. Children as young as 5 can subitize 6 objects, especially looking at a die. However, children with dyscalculia can subitize fewer objects and even when correct take longer to identify the number than their age-matched peers. Dyscalculia often looks different at different ages. It tends to become more apparent as kids get older; however, symptoms can appear as early as preschool. Common symptoms of dyscalculia are, having difficulty with mental math, trouble analyzing time and reading an analogue clock, struggle with motor sequencing that involves numbers, and often they will count on their fingers when adding numbers.
