I have a Jenga set with a colored dot on one end of each piece. The dots are red, green, blue or purple.
Play Jenga as normal. When a player pulls out a Jenga piece, look at the color of the dot. Based on the dot color, the player has to do a specific thing. Examples include:
Red = Name a social skill
Blue = Compliment the person to your left
Green = Recreation Therapist presents a social situation and player says how he would react in that situation
Purple = Set a goal to improve a social skill
