One of Mr. T's goals from his OT is to copy models of all sorts of things: playdoh, blocks of all kinds etc. It helps him develop his visualizing ability which is important for writing and, eventually, spelling among other things.
It's not something he particularly enjoys because it's pretty challenging for him because of his fine motor skills - especially with playdoh. But we keep working on it. Here's something he made the other day (copied from something I made). I'm pretty sure it was supposed to be a cow. Or an elephant.
O Boy was working with us and, true to form, decided to make his own creation rather than copy mine. This is a dancer with a broken arm waving hello. I'm serious.
