Dice monster

Have a set of body part cards and a dice.  You show the first card to the students and they have to say what it is.  Then they take a dice and roll it to see how many of that body part they should draw (for example, draw three heads).  This continues until they have a monster.  For older kids you can get more and more detailed, like 3 eyebrows, 7 toe nails etc.  When they are finished have them write how many of each thing there are, or tell you about their monster.
