This child is gifted. Being very smart, he ended up doing all the work for his group. He thought up all the answers, and he told others what to write on the board. If he was wrong, the whole group was wrong. It was a one person team with 3 children. He was impatient and unkind to lesser intellects.
Such an amazing intellect should be taught to lead because when he grows up, no matter how gifted he is, he alone cannot achieve great things. He needed to be taught to move beyond his own intelligence to harness the collective intelligence of others, even if individually, these others were less intelligent than he.
