The guy has had some issues with getting stuff written in time at school. (We've tried to tell him to just write with worse handwriting and just write the first thing you think of, but he's not willing to do that.) So, we've tried to get him to write at home so that he gets faster at his preferred handwriting quality.
Generally, he's not motivated to do extra writing even when offered a generous amount of pom-poms. (When the pom-poms hit certain levels in the jar, he gets rewards.)
Today, though, he was offered an extra episode of Avatar: The Last Airbender if he summarized the one he just watched. He got right on that, so maybe we'll be good until we run out of episodes.
