How do you explain the opposite of a child?

To explain what is opposite of a child, show them the flash card that represents big/small. In your child’s world, children are often smaller and adults are often bigger. Another way that a child is opposite of an adult is in age. Children’s age is a small number and the age of an adult is a larger number. Ask your child to think of different ways that adults and children are opposite to help them understand this concept.
