Episode Summary
Fragments and run-ons — the bane of every teacher’s grading stack. By the time back-to-school writing assignments roll in, you’ve probably already seen sentences like “Went to the park” or “The dog with a long tail and spots.”
That’s why this episode is all about teaching subjects and predicates. Far from being too “basic,” subjects and predicates are the LEGO blocks of grammar. Without them, everything else — punctuation, clauses, and complex writing — collapses.
In this episode of Commas in the Chaos, I share four tried-and-true strategies for teaching subjects and predicates in upper elementary. You’ll learn why they matter, how to introduce them step by step, and how to make the practice hands-on and engaging so your students don’t just memorize rules, but actually write stronger sentences.

Common pitfalls students face — and how to fix them
Why Subjects and Predicate Matter
Students may think they’re writing complete sentences, but without a clear subject and predicate, their writing quickly becomes a jumble of fragments and run-ons. In grades 3–5, the work expands beyond simply “find the subject” into:
Complete subjects and predicates
Simple subjects and predicates
Compound subjects and predicates
Mastering these is the foundation for building sentences that are strong, clear, and ready for more advanced grammar.
4 Tips For Teaching Subjects & Predicates
Tip #1: Split the Sentence at the Verb
Teach students to find the verb first, then split the sentence in two. Everything before the verb is the complete subject, and everything after is the complete predicate.
Example: The excited kids at recess played tag on the playground.
Complete Subject → The excited kids at recess
Complete Predicate → played tag on the playground
Pro tip: Give students anchor words (is, are, was, were) and let them act out verbs to help them identify the predicate.
Tip #2: Start with Complete Before Simple
Jumping straight into simple subjects and predicates overwhelms students. Start with the complete subject and predicate first to give them the big picture. Once they see the full “chunk,” it’s easier to zoom in later.
Tip #3: Shrink It Down to Simple
After students have mastered complete sentences, introduce the two guiding questions:
Who or what did or is something? → Simple subject
The subject what? → Simple predicate
This repeatable process gives them confidence and consistency.
Tip #4: Make It Hands-On
Grammar sticks when it’s interactive:
Sentence Surgery → Cut apart fragments and run-ons for students to “fix.”
Highlight Their Writing → Circle subjects and underline predicates in their own drafts.
Color Coding → Use two highlighters (one for subjects, one for predicates) to make sentence parts visible.
Common Pitfalls & Fixes
Even with a staircase approach, students will struggle. Some of the most common challenges include:
Missing the verb → Use verb lists and reminders that verbs can be “boring” helpers like is or was.
Underlining only one word → Start with complete parts to reinforce the whole chunk.
Confusing modifiers for subjects → Redirect with guiding questions.
Dropping helping verbs → Remind them that the simple predicate includes the main verb + its helpers.
