DD10 has low working memory as well, no ADHD, but AS and Anxiety Disorder. It's a bit ironic for us, she can quote things she's read word for word (close to photographic memory), but if I ask her to brush her teeth and wash her face, she almost always forgets one or the other. She also still uses a lot of "finger math". Her school did not do "minute math", so it's not something she ever had to stress about, the multiplication tables she doe remember are because we have the schoolhouse rock series, and she can sit and sing the songs to herself. At home we handle it with list making, charts, etc. At school she does homebound this year, so she's one on one with 2 different teachers. This eliminates most of the challenges it would pose in the classroom. I would be interested in hearing if everyone knows of methods to improve WM.
