Grade 3 Grammar

Home > Resources & Worksheets > Grammar > Grade 3

In Grade 3, children begin to develop more complex writing skills, learning how to add detail, variety, and style to their sentences. Two key grammar topics they’ll focus on this year are adjectives and sentence structure. These concepts help children write sentences that are descriptive, clear, and interesting to read.

Typical grammar topics covered in Grade 3 include:

Adjectives - Describing words that add detail to nouns

Sentence Structure - Learning how to build different types of sentences

Compound Sentences - Joining ideas together with conjunctions

Verbs and Tenses - Using past, present, and future correctly

Punctuation - Introducing quotation marks and commas in lists

Expanding Vocabulary - Choosing the best words for meaning and tone

What Are Adjectives?

Adjectives are words that describe nouns. They tell us more about what something looks like, feels like, sounds like, or even tastes like! Using adjectives helps young writers paint a clearer picture in the reader’s mind.

Examples:

The tall giraffe stretched his long neck.

Will wore a bright orange scarf.

The mysterious forest was filled with glowing lights.

Encouraging children to use a variety of adjectives makes their writing more exciting and helps them express ideas with detail and creativity.

Understanding Sentence Structure

Sentence structure refers to how words and phrases are arranged to form a complete thought. In Grade 3, children begin learning how to write different kinds of sentences - simple, compound, and complex - and how to vary them to make their writing flow better.

• Simple Sentence: Has one main idea.

Example: The owl hooted.

• Compound Sentence: Joins two ideas using a conjunction such as and, but, or because.

Example: The owl hooted, and the fox listened carefully.

• Complex Sentence: Adds extra information or detail using clauses.

Example: When the owl hooted, the fox listened carefully from behind the trees.

By learning how to structure sentences in different ways, students can make their writing sound more polished, engaging, and mature.

Adjectives and sentence structure work hand in hand to make writing vivid and enjoyable. These skills teach children how to expand their ideas, connect their thoughts, and bring their stories to life. The ability to build clear, descriptive sentences sets a strong foundation for creative and academic writing in later grades.
