#### Lesson Outline:
**Introduction (10 minutes):**
- **Warm-Up Activity:** Write a few simple and compound sentences on the board. Ask students to identify the differences between them to activate background knowledge.
- **Direct Instruction:** Explain the concept of complex sentences. Define the main clause and subordinate clause. Show examples of complex sentences on the projector/Smartboard. Introduce common subordinating conjunctions (e.g., because, although, when, if, since).
**Guided Practice (15 minutes):**
- **Group Activity:** Divide the class into small groups. Give each group sentence strips with simple sentences and subordinating conjunctions. Have them combine the sentences to form complex sentences.
- **Interactive Writing:** Using chart paper, write a few complex sentences together as a class. Discuss where to place the comma when the subordinate clause comes first.
**Independent Practice (20 minutes):**
- **Worksheet Activity:** Distribute the "Complex Sentences and Punctuation" worksheet. Students will complete sentences by adding subordinating conjunctions and punctuating them correctly. Circulate the room to provide assistance as needed.
- **Notebook Assignment:** In their notebooks, students will write five complex sentences of their own, making sure to use the correct punctuation.
**Review and Closing (10 minutes):**
- **Discussion:** Review the students' work on the worksheet. Select a few students to share their sentences from their notebooks.
- **Q&A:** Address any questions or misunderstandings about complex sentences and punctuation.
- **Exit Ticket:** Ask students to write one complex sentence on an index card and underline the subordinating conjunction before leaving the classroom.
**Homework:**
- Assign students to write a short paragraph (5-6 sentences) on a topic of their choice, including at least two complex sentences and using proper punctuation.
---
**Assessment:**
- Observation during group activity and guided practice.
- Review of worksheet and notebook assignments.
- Evaluation of exit tickets and homework assignments.
---
**Extensions:**
- **Advanced Learners:** Challenge students to transform a paragraph of simple sentences into a paragraph with complex sentences.
- **Struggling Learners:** Provide additional practice with identifying and using subordinating conjunctions through supplementary worksheets or targeted small-group instruction.
---
**Reflection:**
- Reflect on the effectiveness of the lesson. Did students grasp the concept of complex sentences and correct punctuation usage? Were the objectives met? Adjust future lessons based on observations and student feedback.
---
**Additional Notes:**
- Incorporate technology by using educational grammar games or apps that focus on sentence structure and punctuation.
- Encourage students to use complex sentences in other writing activities throughout the week to reinforce learning.
