Many of the kids in therapy work on the skill of opposites. This is a skill children use in many activities once they move into kindergarten. It is also a skill that requires critical thinking and building enriched vocabulary. At home, or in the car, you can play games where you state one word and then your child tries to supply the opposite word. Some easy beginning opposites include: up/down, fast/slow, boy/girl, open/shut, little/big, over/under, mom/dad, brother/sister, hot/cold, off/on, in/out, etc. Sometimes it can help, and be fun, to draw pictures of these items to help solidify the concept in your child's mind.
