Teaching Students What Makes a Complete Sentence
There are a few different vocabulary words to use when teaching students what makes a complete sentence. They are:
- Naming Part (also known as the SUBJECT): This tells who or what the sentence is about.
- Telling Part (also known as the PREDICATE): This tells what the subject is or does.

Students must remember that every sentence they write needs a naming part and a telling part!
Halloween Sentence Building with Subjects & Predicates
To begin, help students build simple sentences with creative subjects and predicates. Use a thematic activity like the one below where there are various naming parts (subjects) and telling parts (predicates). Students love to mix them up and build a variety of silly sentences!

Once students have a strong understanding of what makes a complete sentence, it’s time to work on adding descriptive details. There are a few different ways to help students add more details to their sentences. Think about this boring, short sentence: The ghost hid.
Teach your students how to improve it by adding a few details:
- Add adjectives – The friendly ghost hid.
- Tell where – The friendly ghost hid under my bed.
- Tell when – Last night, the friendly ghost hid under my bed.
- Explain why – Last night, the friendly ghost hid under my bed so he could play with my toys.
Just look at how that sentence transformed!
