To determine the subject and predicate of a sentence, you need to understand basic sentence structure. A sentence is typically made up of a subject and a predicate. The subject is the noun or pronoun that the sentence is about, and the predicate is the part of the sentence that tells us something about the subject.

In this case, the subject is "children." It is the noun that the sentence is about, as it refers to the young individuals who are waiting. The predicate is "are waiting," which tells us what the children are doing.

It's important to note that the word "there" at the beginning of the sentence is not the subject. In English, sentences can have a structure called a "dummy subject," where the word "there" is used as a placeholder to introduce the actual subject, "children" in this case.
