• Supported Practice: Students select the most logical conjunction to show addition, contrast, or choice between 10 varied sentence pairs.
• Independent Practice: The Challenge Round requires students to apply syntactic logic to four more complex items, reinforcing mastery of compound sentence structures.

This resource utilizes the gradual release of responsibility model, moving students from scaffolded instruction to independent application of coordinating conjunctions.

Drawing on Fisher & Frey (2014) research, this Grade 3 worksheet effectively teaches grammar by having students apply coordinating conjunctions (and, but, or, so, yet) in sentence composition. The 14 sentence-combining tasks deepen understanding of how these function words signal logical relationships. An included answer key provides immediate feedback, crucial for mastery. This resource assesses student readiness for complex writing, scaffolding them toward sophisticated syntax as required by Common Core.
