Thank you for your thoughtful response, Dottie. He's good at math but not great. He's in 5th grade and currently scores like an average (in our district) end of the year 6th grader. He doesn't love math. Thank you also, Knute974. You bought up a good point! smile More to think about.... A big problem with my DS is when he knows the material, he becomes a huge behavior "issue" for the teacher and class. Will this distruptive behavior ever stop when he's older but subjected to material he already knows? How often do these kids end up maturing, recognizing limits, and just "adjusting" .... Do they ever?....
