Is there anything in the text book that you think would interest your son? Perhaps you can help out by prescreening selected topics that you think he would enjoy? The problem with 6th grade math is that it's doesn't even plan to introduce new concepts - just consolidate and get a firm foundation for Pre-Algebra. Consolidating might be needed, but it isn't by nature, fun. If it isn't needed, then moving on might be best.

Best Wishes,
