I started this thread on the main board, but I should have come here first. :)
We have been HS since December. My son lacks a short term memory. We actually removed it during a brain surgery. So, no short term or working memory. His visual memory, however, is good. And, I am seeing that with rote memorization, slowly, eventually, some things bank into long term. Math is a huge struggle. He can memorize basic facts(like single digit multiplication), but when he has a problem with more than one step(borrowing/regrouping more than once in 2-3 digit subtraction), he missteps, forgets. And, I am finding that he does not understand the mathematical concepts at all. He does not know why he is borrowing in subtraction. He doesn't understand why he carries the 1 in addition. He doesn't see how division and multiplication are related. He can understand whether to use subtraction or addition or multiplication in word problems. In working with him, I already know that a rote memory approach is best for math, and mastery, not spiral. I am actually considering Kumon for the rote memorization/practice he needs. BUT, I need a curric that addresses his conceptual problems.
What I am looking for his a multi-sensory math program that will help him understand the concepts of math. The WHY, HOW. Etc. His visual memory is good, so I need something that incorporates the senses. Any help is appreciated.
Thanks
