Printable Coordinating Conjunctions Worksheet | Grade 3 ELA

This Grade 3 coordinating conjunctions worksheet provides students with 15 structured problems to master combining independent clauses into clear, compound sentences. By practicing with the 'FANBOYS' (for, and, nor, but, or, yet, so), learners develop the syntactic complexity required for fluent writing. Answer key included for immediate feedback. Aligned to CCSS.ELA-LITERACY.L.3.1.H.

What's Inside

This comprehensive five-page PDF features 15 targeted tasks divided into three distinct sections. Part 1 focuses on sentence combination through rewriting; Part 2 utilizes multiple-choice selection to determine the best contextual conjunction; and Part 3 challenges students to fix sentence pairs by adding both the comma and the appropriate coordinating word. A clear "Remember" anchor box on the first page provides a visual reference for the seven coordinating conjunctions, and a full answer key is included for teacher or parent use.

Skill Progression

• Guided Practice: The first page introduces 1 sentence combination task with a clear visual bank of FANBOYS to scaffold initial attempts.
• Supported Practice: 4 multiple-choice problems allow students to analyze which conjunction logically connects two ideas before they have to generate the text themselves.
• Independent Practice: 10 total rewrite problems require students to apply comma rules and conjunction selection simultaneously in their own handwriting.

This resource follows a gradual-release model, moving from identifying the correct word to the high-level application of combining original thoughts into cohesive compound structures.

Standards AlignmentPrimary Standard: `CCSS.ELA-LITERACY.L.3.1.H`. Use coordinating and subordinating conjunctions. This worksheet specifically targets the coordinating aspect of the standard, ensuring students understand how to link two complete thoughts to create more sophisticated sentence structures. Supporting Standard: `CCSS.ELA-LITERACY.W.3.4`. With guidance and support from adults, produce writing in which the development and organization are appropriate to task and purpose. Both standard codes can be copied directly into lesson plans, IEP goals, or district curriculum mapping tools.

How to Use It

Use this worksheet as a focused practice session after a direct instruction lesson on compound sentences. It works exceptionally well as a morning work assignment or a literacy center rotation. During instruction, observe if students remember to place the comma before the conjunction; this is a common formative assessment point for third graders. The 15 problems typically take 20 to 30 minutes to complete depending on student writing speed.

Who It's For

This resource is designed for Grade 3 students but is also suitable for Grade 4 review or for Grade 2 students ready for extension. It provides excellent support for English Language Learners (ELL) who are learning the logical relationships between clauses. It pairs naturally with a mentor text containing compound sentences or an anchor chart displaying the FANBOYS acronym.

The standard CCSS.ELA-LITERACY.L.3.1.H requires third-grade students to demonstrate command of the conventions of standard English grammar and usage when writing, specifically using coordinating conjunctions. Research from Fisher & Frey (2014) emphasizes that the gradual release of responsibility—moving from the provided anchor box to independent sentence generation—is essential for students to internalize complex grammatical structures. This worksheet applies those principles by providing 15 tasks that transition from recognition to production. By mastering these connections, students move beyond simple sentence construction toward the varied sentence lengths rewarded in upper-elementary writing rubrics. This structured approach to conjunction practice supports the development of syntactic maturity, which is a strong predictor of overall reading comprehension and writing quality in later grades. The inclusion of a formal answer key ensures that learners receive the immediate corrective feedback necessary to prevent the fossilization of grammatical errors during the independent practice phase.
