  4. How to identify students with dyscalculia It is possible for evaluators to determine if a child has dyscalculia through general types of diagnostic math assessments, reviews of student work, and cognitive assessments. DyscalculiaScreener is a PC-based program designed for educators and therapists seeking to identify dyscalculic tendencies in their students, ages 6-14

  5. Causes • Weakness in visual processing • Deficits in working memory • Difficulty sequencing or organizing information • Developmental problem associated with the inferior parietal lobe. • Genetic factors. • Developing a phobia of math

  6. Instructional Techniques and Accommodations • Always move from instruction to restricted practice, in which it is hard for the pupil to make an error. • Ask lots of specific questions to explore learning. • Constantly change the methods of teaching to suit the situation. • Correct all errors and give hints rather than straight answers.

  7. Instructional Techniques and Accommodations • Encourage shared learning. • Use visuals and key words as reminders of the whole skill or topic that has been taught. • Use a multisensory approach: free math songs http://www.kidsknowit.com/educational-songs/index.php?topic=Math http://www.songsforteaching.com
