Great concept for teaching about the human body! You could make it more complex with a more accurate skeleton. Rather than a die, have a bag with names of bones and pick up the corresponding bone. This could be done with other systems of the body as well, such as the digestive system.
Stack the bones if you dare. Fun stacking Halloween game challenges you to remove a bone from the bottom and restack it on top without toppling over the tower. Includes painted wood blocks shaped like bones, instructions and a cute skull to set on top of the stack.
