From our teachers' playbook

Who did it, what happened, period!

What do 3rd graders learn about sentences?

Third graders learn that every complete sentence needs two parts: a subject (who or what) and a predicate (what they do or are). The hungry puppy | chewed my shoe. They sort sentences into four kinds: telling, asking, commanding and exclaiming, and they match each one with the right end mark. They fix fragments and run-ons, and start joining two simple sentences with words like and, but and so to make compound sentences. The click moment is when kids can read their own writing and hear where a sentence is missing a piece.

Our favorite ways to teach sentences

Good sentences are the building blocks of good writing, so we give kids lots of chances to build, sort and fix them.

Split it down the middle

Write a sentence on a sentence strip and literally cut it between the subject and the predicate. Mix up a pile of halves and let kids build new, silly sentences like "My teacher | swam across the lake." Then they practice on the subject and predicate worksheet.

Why it works: showing first, practicing together, then letting kids try alone is the "gradual release" model teachers have relied on for decades (Pearson and Gallagher, 1983).

Name that sentence

Read a sentence aloud with expression and kids hold up a card: period, question mark or exclamation point. Then ask which kind it is. A quick daily round builds the habit fast.

Why it works: researchers who compared ten study methods found practice testing is one of the two that work best (Dunlosky and colleagues, 2013).

Be the editor

Give kids a short paragraph with missing capitals, missing end marks and a run-on or two. They fix everything with a colored pen. Mixing all the sentence errors together is what prepares them to edit their own writing.

Why it works: shuffled practice teaches kids to choose the right strategy, not just repeat one, and it improved test scores in research (Rohrer and Taylor, 2007).

Questions teachers and parents ask

What makes a complete sentence in 3rd grade?

A complete sentence has a subject, a predicate and expresses a full thought. It starts with a capital letter and ends with a period, question mark or exclamation point.

What are the four types of sentences?

Declarative sentences tell something, interrogative sentences ask, imperative sentences give a command and exclamatory sentences show strong feeling. Third graders often learn them as telling, asking, command and exclaiming sentences.

What's the difference between a fragment and a run-on?

A fragment is missing a part, like "Ran to the bus." A run-on squeezes two sentences together without the right punctuation. Kids fix fragments by adding the missing piece and fix run-ons by splitting or joining them correctly.

How do I help my child write better sentences?

Have them read their writing out loud. Kids often hear a missing word or a run-on before they see it. Then ask, "Who is this about, and what did they do?"

Do 3rd graders learn compound sentences?

Yes, many 3rd graders start combining two simple sentences with words like and, but, or and so. It's a big step toward more interesting writing.
