What to watch:

Learning objectives

Recognize a complete sentence and a fragment.
Identify the subject and predicate.
Use a capital letter and an appropriate end mark.
Build statements, questions, and exclamations.

The core patterns

Statement: Maya reads a book.

Question: Does the dog run quickly?

Exclamation: My robot dances happily!

What every sentence needs

A complete thought: “The baby sleeps.” makes sense by itself.
A subject: who or what the sentence is about.
A predicate: tells what the subject does or is.
Writing signals: a capital letter and an end mark.

Try these experiments

Move Build stage from a subject fragment to a full sentence.
Change the subject and action; watch both parts of the cartoon update.
Compare a statement, question, and exclamation.
Tap a sentence word to identify its job.

Common misconceptions

A long group of words is not automatically a sentence.
A sentence needs a complete thought, not only punctuation.
The subject may contain more than one word, such as “The dog.”
Questions end with ?, while strong exclamations end with !.
