A very specific difficulty in mathematics, often with numeracy, but no accompanying difficulty with literacy.
What to look for: pupils may have difficulty in remembering and carrying out sequenced instructions, they can confuse telephone numbers. They might have problems with word sums or in problems following procedures in problem-solving. They might have difficulty recognizing patterns or they might write numbers the wrong way around. They sometimes muddle digits and operators and have poor estimation skills. They may lack confidence and have low self-esteem during maths lessons and may work slower than others.
