Have you read anything by Dr. Linda Silverman and visual spatial learning?
I ask because I have a kindergarten, vsl, eg/pg DS6. I've found that repetition and practice with math is detrimental and causes problems. He's a vsl and he doesn't tend to function well under timed tests or rote with math. Dr. Linda Silverman's research has supported this argument.
Last year, my son was at a gifted school where he was able to accelerate in the math workbook at his own pace. He quickly completed the pre-k/k/1st grade curriculum in math within 2 1/2 months. He learned how to multiply from a visual illustration and with no instruction or practice. This year, he's at a different gifted school and they use
https://www.xtramath.org/ and he's refusing to go beyond adding. Part of it is motivation and math being boring and no longer fun, but I think there's possibly more to the story. Next year, I plan to homeschool him because he used to love math.
I find your question and finding interesting. I find my son can pick up things by observing (visual!) and without practice in some cases. He doesn't always learn in a linear or sequential fashion either (another vsl trait!) and yet math instruction is aimed in this manner.
Part of problem seems to be that some eg/pg people tend to rely more heavily on either the right or left hemisphere of the brain and this affects how they learn, worldview, etc. - yet much of the gifted literature (from what I've read) doesn't seem to address how this can impact with learning, worldview, etc. I also wonder if some kids treat it as 'playing' with video games or equivalent and end up becoming enraptured with math.
