Subject-Verb Agreement Printable Worksheet | Grade 3 ELA

This Grade 3 grammar worksheet helps students master the complex rule of subject-verb agreement when extra words come between the subject and the verb. By focusing on identifying the true subject of a sentence, students learn to ignore distracting prepositional phrases or appositives to ensure proper sentence structure and clarity in their writing.

• Best For: Independent practice and grammar reinforcement
• Time: 15–20 minutes

What's Inside: This comprehensive 3-page PDF includes a clear instructional header with visual examples, followed by 12 targeted practice problems. The tasks are divided into three distinct sections: multiple-choice verb selection, fill-in-the-blank application, and original sentence generation. A full answer key is provided to facilitate quick grading or student self-correction.

Skill Progression

• Guided Practice: The first page provides a visual anchor and clear examples, such as "The bouquet of flowers is beautiful," to demonstrate how to isolate the subject from the intervening phrase.
• Supported Practice: Part 1 contains 6 problems where students are explicitly prompted to underline the real subject and circle the correct verb, reinforcing the mechanical steps of the rule.
• Independent Practice: Parts 2 and 3 require students to supply their own verbs and eventually draft two original sentences, moving from recognition to generative mastery.

This sequence follows the gradual-release model, ensuring students build confidence before being asked to apply the rule in their own creative writing.

Standards Alignment

This resource is specifically aligned to CCSS.ELA-LITERACY.L.3.1.F, which requires students to ensure subject-verb and pronoun-antecedent agreement. It also supports L.3.1.A by reinforcing the function of nouns and verbs within complex sentence structures. Both standard codes can be copied directly into lesson plans, IEP goals, or district curriculum mapping tools.

How to Use It

Use this worksheet during the "You Do" phase of a grammar lesson after introducing the concept of intervening phrases. It works exceptionally well as a formative assessment tool; as students work through the 12 tasks, observe whether they are correctly underlining the subject or if they are being distracted by the noun closest to the verb. Expect most students to complete the three pages within 15 to 20 minutes.

Who It's For

This resource is designed for third-grade students but is also highly effective for fourth-grade review or for English Language Learners (ELL) who struggle with the nuances of English syntax. It pairs naturally with a mentor text passage where students can search for similar sentence structures after completing the worksheet.

Research from Fisher & Frey (2014) emphasizes the importance of the gradual release of responsibility model in grammar instruction. This worksheet aligns with CCSS.ELA-LITERACY.L.3.1.F by isolating the specific challenge of intervening prepositional and appositive phrases, which often trigger agreement errors in developing writers. By requiring students to first identify the "real" subject before selecting a verb, the resource builds the metacognitive habits necessary for self-editing. According to NAEP data, mastery of complex sentence structures in early elementary grades is a strong predictor of later writing proficiency. This 3-page resource provides the structured repetition required to move from recognition to independent production. The inclusion of a "Make Your Own" section ensures that students apply the rule in a generative context, solidifying the connection between grammatical rules and active communication.
