I know of a kid who had dyscalculia in the local PS and they accommodated him very well. The teacher used manipulatives to teach numeracy for every concept. They used blocks, counting bears, cuisenaire rods, play money, abacus etc. They tried to teach counting forwards and backwards using manipulatives until 3rd grade. I used to volunteer in the classroom at that time - I saw the teacher use piles of counting bears to teach 5x4 - ask the child to make 4 piles of 5 bears - I also saw her tell the child that multiplication was repeated addition several times.
The parent of that child (who was also a classroom volunteer) told me that school district provided funds for a lindamood bell math program and that they worked on visualizing math concepts in those sessions. I was later told that around 5th grade, this child went "mainstream" in math as the child had all the tools needed to handle basic math due to the interventions in the earlier grades.
