Most of my students love dice games and I've found many "Roll A..." games online. It gets even the most reluctant pencil user to draw. Since it's Halloween season, in some individual and group OT sessions, we've been playing "Roll A Monster".
The students roll a die, then call out the number represented by the number of dots on the die. This ability is called "subitizing" (to perceive at a glance the number of items presented) and is a wonderful math skill! Then student then finds the intersection of their number and the part they are working on.
Together, we focus on the detail in the drawings, the proportion of the pieces, and the orientation and location of the body parts. We are also working on pencil pressure and drawing lightly enough to fully erase our lines. The students love seeing the goofy monsters they come up with! I've included some of the monsters I've rolled (as models) so you can see a few of the possibilities.
