Learning Goals & Success Criteria

I can…

• Identify what makes a compound sentence.

• Write clear compound sentences to express connected ideas.

Success Criteria:

• I explain why two simple sentences can be joined with a conjunction.
• I correctly use coordinating conjunctions to combine two related ideas.
• I check my sentences to ensure they have correct punctuation (comma before the conjunction).
• I recognise compound sentences when reading.

Materials Required

• Whiteboard and markers
• Sentence strips
• Coordinating conjunction posters (FANBOYS)
• Worksheets with sentence building exercises
• Laptops/tablets (optional, for interactive activities)
• Exit ticket slips

Detailed Lesson Plan

1. Introduction (10 minutes)

Objective: Activate prior knowledge about sentences and introduce compound sentences.

• Begin with a quick review of what a sentence is and difference between simple and complex sentence forms.
• Write two simple sentences on the board:
  • The dog runs.
  • The cat sleeps.
• Ask students if they can join these two ideas into one sentence.
• Introduce the term compound sentence and explain it is made by joining two simple sentences (independent clauses) using a coordinating conjunction.
• Show the FANBOYS acronym for conjunctions (for, and, nor, but, or, yet, so).
• I can statement: "I can understand that a compound sentence joins two simple sentences with a conjunction."

2. Guided Practice (20 minutes)

Objective: Identify and construct compound sentences using FANBOYS conjunctions.

• Distribute sentence strips with simple sentences (e.g., She likes ice cream. / He likes cake.).
• In pairs, students will use a conjunction strip to join sentences into compound sentences.
• Model one example with the whole class: She likes ice cream, and he likes cake. (underline conjunction and point out comma before conjunction.)
• Use an interactive whiteboard or chart paper to write student examples and discuss correctness.
• Discuss the meaning changes if different conjunctions are used. For example, but shows contrast, and shows addition.
• Success Criteria Check: Each pair says their sentence aloud and explains why they chose that conjunction.

3. Differentiated Writing Activity (25 minutes)

Objective: Write compound sentences independently.

• For On-Level Learners: Write 5 compound sentences using sentence starters given by the teacher; emphasise use of commas and conjunctions.
• For Struggling Learners: Sentence frames provided:
  • "I like ____, but ____."
  • "She _____, and he _____."
    Use word banks with familiar vocabulary related to Nunavut (animals, environment, community).
• For Advanced Learners: Challenge to write compound sentences with different conjunctions and try to explain how the meaning changes.
• Teacher circulates to provide support, scaffold ideas, and offer extension prompts.
• Peer editing: Partners check if sentences have two independent clauses joined by an appropriate conjunction and correct punctuation.

4. Wrap-Up and Reflection (10 minutes)

• Conduct a quick oral exit ticket: Each student says a compound sentence with correct structure and tells which conjunction they used.
• Reflect on the success criteria: "Did I join two ideas with a proper conjunction? Did I write a compound sentence?"
• Recap why compound sentences help make writing clearer and more interesting.
• I can statement: "I can say and write compound sentences using conjunctions correctly."

---

Assessment and Feedback

• Observe student participation during partner and individual work.
• Check written work for correct sentence structure, conjunction use, and punctuation.
• Use exit tickets as formative assessment to gauge understanding.
• Provide oral and written feedback highlighting use of conjunctions and sentence combining skills.

---

Differentiation and Inclusion Strategies

• Provide visual aids (FANBOYS chart, sentence strips) for visual learners.
• Use pair share activities to build social and linguistic confidence.
• Provide sentence frames and word banks for ELL or below reading level learners.
• Offer extension challenges for advanced learners to deepen grammar understanding.
• Use vocabulary and sentence examples relevant to Nunavut context to engage students culturally.

Extension Idea (Optional Homework)

Ask students to find or write 3 compound sentences from favourite books, comics, or their daily conversations. Bring examples to discuss in the next class.

This lesson plan balances explicit grammar instruction with contextualized and differentiated activities, in line with Ontario’s curriculum for Grade 5 English Language Arts, and pays respectful attention to the students’ reading levels and cultural environment in Nunavut.
