Your child has probably noticed that some letters reach above the middle space on her lined paper, some stay inside it and some dip below it. In this game, you translate the way letters look into body positions. For tall letters, you jump up; for medium-sized ones, you stand in place; and for ones that drop down, you crouch. So for bag, you jump up for b, stand still for a and crouch for g.
To start playing, write down a list of words. Then take turns choosing one and acting it out to see if the other person can guess what it is.
