Working memory is short term memory. It is the ability to memorize something and then keep it in your head so that you can use the information to carry out a task. Students use working memory when they are recalling facts, paying attention, following instructions, taking notes, and solving various problems. They are using their working memory throughout the school day.
Visual memory is when we see objects, numbers, letters, pictures, etc and we can recall it. Students who struggle with visual memory struggle to remember the detail, copy work down, read, and do mental computations.
Auditory memory is keeping and using information that has been given verbally. Students who need more practice in this area usually have trouble learning to read using phonics and when they do read they have a hard time processing what they read.
