 A useful skill for young children is comparing sizes. One way to do this is by talking about biggest and smallest. Say you have some buttons. You can ask your child to point to the biggest one and then they can find the smallest one. You can do this just about anywhere with all kinds of different objects like bears and fuzzy pom poms. Just ask your child to point to the biggest one and the smallest one of each certain type of object. Doing this will help your child develop their ability to compare things.
