He practices piano from his piano lessons, but those are very casual (it's a class specifically geared to preschoolers/kindergarteners, not the tradition doing scales stuff.) The teacher was very clear that practice was optional and should be kept short and fun.
The teacher of his arts & crafts class at the rec center let us take home a project that some of the students hadn't gotten to yet. She just thought they might enjoy it though, and isn't going to check up on who did it and who didn't. Some students just declined to take it with them and that was fine.
