Show children the real thing, compare ten lollipops with two lollipops, show them which one is more, and then tell them that more is bigger. Ten lollipops are more than two lollipops, so ten are bigger than two.

Mom and dad can compare the number greater than and the number less than to be a little monster, and tell their children that this little monster likes to eat big numbers, and whoever is bigger than his big mouth (mouth larger than numbers, mouth smaller than numbers) will face and eat who. Teaching children in this way is easy to understand.
