Printable Grade 3 Conjunctions: And, But, Or, So Worksheet

This comprehensive Grade 3 ELA worksheet focuses on mastering coordinating conjunctions—specifically "and," "but," "or," and "so." Students will learn to connect ideas logically within sentences and across a narrative passage. By completing these structured exercises, learners develop the syntactic complexity required for fluent reading and cohesive writing in early elementary grades.

This two-page resource contains 15 targeted practice opportunities. The first page features a high-interest narrative story titled "The Picnic," requiring students to insert the correct conjunction into 10 distinct blanks within a story context. The second page provides a "Quick Hint" reference guide followed by 5 "Extra Practice" sentences to solidify understanding of joining, contrasting, and result-based words.

Zero-Prep Workflow

The "classroom-ready" design ensures immediate utility for busy educators. First, print the two pages back-to-back (30 seconds). Second, distribute the worksheets during your grammar block or as a quick transition activity (30 seconds). Third, review the "Quick Hint" section together before students work independently or in pairs (1 minute). The total teacher preparation time is under two minutes, making this an ideal solution for emergency sub plans or last-minute literacy centers.

Standards Alignment

This worksheet is directly aligned to CCSS.ELA-LITERACY.L.3.1.H, which requires students to "use coordinating and subordinating conjunctions." By practicing the specific functions of "and" (joining), "but" (contrast), and "so" (result), students meet the fundamental requirements of this grammar standard. This standard code can be copied directly into lesson plans, IEP goals, or district curriculum mapping tools.

How to Use It

Use this resource during the "independent practice" phase of a lesson on compound sentences. As students work through the narrative passage, observe if they can distinguish between the contrast of "but" and the result of "so"—this is a vital formative-assessment point. Alternatively, assign the second page as a quick "exit ticket" to gauge mastery before moving on to complex structures. Expected completion time is roughly 25 minutes.

Who It's For

This worksheet is designed for third-grade students moving beyond simple sentence structures. It is also an excellent intervention tool for fourth graders needing a refresher. Pair this resource with a mentor text or an anchor chart highlighting the "FANBOYS" acronym to provide visual support for English language learners and struggling writers.

This Grade 3 grammar resource is architected to support the development of syntactic maturity as outlined in the CCSS.ELA-LITERACY.L.3.1.H standard. Correctly utilizing coordinating conjunctions like "and," "but," "or," and "so" is a foundational skill for producing the compound sentences required for grade-level writing proficiency. According to research by Fisher & Frey (2014), the gradual release of responsibility—moving from the guided narrative context of "The Picnic" to the independent practice sentences—is a proven instructional strategy for skill retention. By focusing on the semantic functions of these "joining words," the worksheet helps students bridge the gap between simple speech and academic writing. Educators can confidently integrate this standard-aligned tool into their literacy blocks to ensure students achieve the linguistic precision necessary for complex communication and advanced reading comprehension.
