I had started another thread on math/writing one's work. Things have been smoother since DS was accelerated another year in math. However, yesterday, I found a note on returned homework next to a word problem that required multipling something like 6x72. "X, you must communicate how you arrived at the answer."

The work, of course, was in his head. Sigh.

On the plus side, most of the work is indeed more challenging and he's less inclined to fuss over coming up with the required text...
