From our teachers' playbook

Who did what? Write it complete!

What do 3rd graders learn about writing sentences?

Third graders learn that every complete sentence needs a subject (who or what) and a predicate (what they do or are). They spot fragments like "Ran to the park" and fix them: "My dog ran to the park." Kids write the four types of sentences: statements, questions, commands and exclamations, each with the right end mark. They also start combining ideas with compound subjects and predicates: Sam and Mia ran and jumped. The click happens when kids reread their own writing and catch their own fragments.

Our favorite ways to teach sentences in 3rd grade

Strong sentences make strong writers. These moves help 3rd graders build them on purpose.

Who plus did what

Give kids a stack of subject cards and predicate cards. They match them to make complete sentences, some silly and some serious. Then they write their favorite three. Building sentences from parts makes the two-part rule stick.

Why it works: the U.S. Department of Education's guide for teaching elementary math recommends moving from hands-on objects to drawings to numbers.

Fix the fragment

Write a fragment on the board and ask, "What is missing: the who or the what happened?" Fix it together, then let kids fix three on their own. Ask the same question every time, and kids start asking it about their own writing.

Why it works: handing over the work step by step, from teacher to student, is one of the most widely used teaching frameworks (Pearson and Gallagher, 1983).

Name that sentence type

Read a sentence aloud with expression and kids hold up a card for statement, question, command or exclamation. Then they say which end mark it needs. Fast, fun and it covers punctuation too.

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

Questions parents and teachers ask about 3rd grade sentences

What makes a complete sentence in 3rd grade?

A complete sentence has a subject (who or what) and a predicate (what they do or are), starts with a capital letter and ends with a punctuation mark.

What are the four types of sentences?

Statements tell something and end with a period. Questions ask and end with a question mark. Commands tell someone to do something. Exclamations show strong feeling and end with an exclamation point.

How do I help my child stop writing fragments?

Have them read each sentence aloud and ask, "Who did it, and what did they do?" If one part is missing, it is a fragment. Reading aloud catches most of them.

What is a compound subject?

A compound subject has two or more subjects that share the same predicate, like "Max and Lily played tag." Combining sentences this way makes writing smoother.
