Counting has rules that apply to any collection.

Thanks to TV shows like Sesame Street, many children enter preschool chanting or singing the number names from 1 to 20. Learning to count meaningfully requires both memorizing arbitrary terms or number names (rote counting) and rule-governed counting (rational counting). Rote recitation of the number words is not the same as having a good number sense for what 20, 25, or 100 means.
