I fully admit my fault in not forcing S7 to sit still and complete his homework assignment. He is good at math, excellent in his reading skills and is very ambitious in his artwork. He's very bright and loves stories, and he can even come up with his own stories verbally, but he has difficulty writing sentences. It bores him and his fine motor skills are just not what they need to be for him to write legibly. He wants to avoid activities he does not excel at.
Getting S7 to sit down and write three complete sentences is a bit of an ordeal -- it can literally take hours. In the end, I got him to write two sentences and draw an accompanying picture. W said what he wrote was not readable, so she had him start over. By the time S7 was through, it was over an hour and a half past his bedtime.
