The book, What’s What? A Guessing Game by Mary Serfozo, allows you to discuss the concept of opposites with your child. Use questions like, “What is soft?” and “What is cold?” to ask your child what he or she thinks those words mean. These conversations help enrich your child’s vocabulary and understanding of what opposites are. Vocabulary means knowing the names of things, concepts, feelings, etc., and it is one of the six early literacy skills that children need to develop before learning to read.
