Several people requested a mind map for Dyscalculia (often called "math dyslexia"). Many students, including my younger sister, have both dyslexia and dyscalculia. Things that may seem simple to others, like number lines or chronology, are difficult concepts for students with dyscalculia.
A poster, showing some of the difficulties pupils with dyscalculia may face. The list of difficulties is not exhaustive but is a flavour of some of the issues. Based on our popular mind map presentation.
