{{hugs}} I know what u mean. 5th grade math is not the solution. (but nevertheless, Ds9 enjoyed his time with the 5th graders for that one month... although he wasn't learning anything new).

Another option:- this worked for Ds9 in his previous school. He did online math during math class time. Once a week after school, a high school student sat down with him for 30 minutes just to talk abt Math. He really enjoyed the time.
