What age do you teach opposites?

Children can begin practicing the concept of opposites around the age of 3 and should have a good understanding of opposites by the time they are 4.  Use flash cards and every day activities to talk about opposites with your child.  Show your child a flash card and ask if they can name the opposite. This type of learning is important as kids are developing critical thinking skills and also helps as they are learning to follow directions and engage in their own daily routines.
