I finally sent my DS' WISC report to his principal and his teacher.  I got a response from the principal one day later.  She's already talked to DS' teacher and sounded like they've already come up with some kind of plan.  
We set up a time to meet this Friday.  She asked if I am Ok with him to take the grade 2 MAP test on math before we meet because they want to have a more updated information on math abilities.  I agreed.  DS told me that a teacher (I believe is the special ed/gifted teacher) asked him to do some math questions (additions and subtractions) yesterday.  He'll probably take the MAP test in the next couple of days.  
I am happy that the school responded quickly on this matter.  I am not 100% sure if they already have a plan in mind or will be discussing different options with me and ask for my suggestions.  Either way, I hope they are flexible with the plan and the plan will truly work for my DS.
