Due to which of the following disabilities, learners have difficulty in understanding concept of quantity and fractions?

Correct option is D

Dyscalculia is a specific learning disability that affects a person's ability to understand and work with numbers, including concepts like quantity, fractions, and basic arithmetic. Learners with dyscalculia struggle with:
· Grasping numerical concepts and relationships.
· Performing basic calculations.
· Understanding mathematical symbols and processes.
Information Booster 1. Dyscalculia affects approximately 3–6% of the population.
2. Symptoms include difficulty in counting, estimating, and understanding numerical patterns.
3. Visual-spatial aids, multisensory teaching, and structured practice help manage dyscalculia.
4. Unlike general math anxiety, dyscalculia is a neurological condition.
5. It is crucial to differentiate dyscalculia from poor mathematical performance caused by other factors, such as lack of instruction or practice.
Additional Knowledge · (a) Dyslexia: This learning disability affects reading and language processing. Learners may have difficulty decoding words, spelling, and comprehending written text, but it does not directly impact numerical understanding.
· (b) Dyspraxia: Dyspraxia primarily affects motor coordination and spatial awareness. Students with dyspraxia might face challenges in writing or handling objects but do not exhibit a specific difficulty with numerical concepts.
· (c) Dysgraphia: This condition affects writing skills, such as handwriting, spelling, and composition. Learners with dysgraphia might struggle with written math problems due to difficulties in writing, but their understanding of numerical concepts is typically intact.
