Looking at Writing: Third Grade

On this page:

During third grade, children are really flexing their “idea” muscles and learning to express those ideas in more sophisticated ways. Sentences are getting longer and more complex. Kids are learning to use a dictionary to correct their own spelling. Grammar improves; for example, you’ll see appropriate punctuation, contractions, and correct subject-verb agreement. 

Third graders can write an essay with a simple thesis statement, examples and supporting details, and a thoughtful concluding sentence. They are building skills in the writing process — research, planning, organizing, revising, and editing (with help from teachers and peers).

Watch a lesson on sentence expansion (whole class)

In this writing lesson, Maria Bailey, a literacy support teacher at Riverside Elementary School in Toledo, Ohio, works with students on sentence expansion — adding details to make sentences more interesting and informative. Students answer the question “why?” with some help from the word “because” to elaborate on a simple idea. The lesson begins with the whole group, then students work in partners, and finally they write expanded sentences independently. In writing longer sentences, students build their understanding of sentence structure. (From our sister project Reading Universe (opens in a new window))
