Overview

This 2-day lesson sequence builds 4th graders’ understanding of clauses and complex sentences following the Common Core State Standards. The "I do, we do, you do" gradual release model ensures scaffolded learning to make a challenging concept accessible and engaging for 9-10 year olds. Each day’s 20-minute session includes clear success criteria and differentiation strategies.

Day 1: Understanding Clauses

Standards

• CCSS.ELA-LITERACY.L.4.1.B: Use a comma before a coordinating conjunction in a compound sentence.
• CCSS.ELA-LITERACY.L.4.1.D: Recognize and correct inappropriate shifts in verb tense.
• CCSS.ELA-LITERACY.L.4.1.A: Use correct capitalization, punctuation, and spelling when writing.

---

Learning Objectives

• I can identify independent and dependent clauses in sentences.
• I can explain the role of clauses in making complex sentences.

Success Criteria

• I can correctly underline independent and dependent clauses in sentences.
• I can say why a clause is important in a sentence.

---

Materials

• Sentence strips with sample sentences
• Whiteboard & markers
• Clause sorting cards (independent vs. dependent)

Lesson Plan

Time	Activity	Details	Notes for Differentiation
4 min	I Do (Modeling)	Teacher explains what a clause is, then shows examples on whiteboard. Uses color-coding (red for independent, blue for dependent).	Use simple, relatable sentences. Visual aids support ELL students.
6 min	We Do (Guided Practice)	Teacher and students sort clause cards together into independent and dependent piles. Talk aloud reasoning.	Provide sentence stems for students who need language support (e.g., “This clause can stand alone because...”).
8 min	You Do (Independent Practice)	Students underline clauses in their own sentence strips and label them I (independent) or D (dependent). Teacher circulates to assist.	Students with IEPs can work with a partner or on fewer sentences; advanced learners write one new complex sentence each.
2 min	Wrap-up & Review	Quick oral review using “I can” statement. Confirm success criteria met.	Positive reinforcement for effort regardless of accuracy.

Day 2: Building Complex Sentences

Standards

• CCSS.ELA-LITERACY.L.4.1.B: Use a comma before a coordinating conjunction in a compound sentence.
• CCSS.ELA-LITERACY.L.4.1: Explain the function of conjunctions, prepositions, and interjections in general and their function in particular sentences.
• CCSS.ELA-LITERACY.L.4.3.A: Choose punctuation for effect.

---

Learning Objectives

• I can create complex sentences using independent and dependent clauses.
• I can correctly use subordinating conjunctions and proper punctuation.

Success Criteria

• I can combine two simple sentences into one complex sentence using subordinating conjunctions (because, since, although, if).
• I can use commas correctly when needed in complex sentences.

---

Materials

• Sentence pairs on cards
• Chart of common subordinating conjunctions
• Student writing journals or paper

Lesson Plan

Time	Activity	Details	Notes for Differentiation
5 min	I Do (Modeling)	Teacher models combining two simple sentences into one complex sentence using a subordinating conjunction; writes on whiteboard. Emphasizes punctuation.	Model with clear, easy examples. Visual checklist of conjunctions for ELL students.
7 min	We Do (Guided Practice)	Students work with teacher to combine sentence pairs into complex sentences aloud. Teacher writes one or two examples on whiteboard with student input.	Pair ELL or struggling writers with stronger peers. Provide sentence frames (“I combined ___ and ___ using ___ because ___.”)
6 min	You Do (Independent Writing)	Students choose one pair of sentences and write a complex sentence in their journal using a subordinating conjunction and correct punctuation.	Writers who finish early write an additional complex sentence with a different conjunction.
2 min	Share & Reflect	Volunteers share their sentences. Class votes if sentence meets success criteria. Teacher highlights correct use of clauses and punctuation.	Celebrate all efforts; provide supportive correction privately if needed.

Differentiation Strategies

• For Diverse Learners: Provide visual aids, sentence stems, and cooperative learning opportunities. Use multisensory instruction (color-coding, oral repetition).
• For Advanced Learners: Challenge to create compound-complex sentences or explain why different conjunctions change sentence meaning.
• For English Language Learners: Provide targeted vocabulary support and model pronunciation of conjunctions.

---

Extension Activities

• Create a “Clause Detective” journal where students find and write complex sentences from their daily reading.
• Write a short story or paragraph using at least five complex sentences with correctly punctuated clauses.
• Hold a “complex sentence contest” to see who can write the most interesting sentence using subordinating conjunctions.

This engaging, scaffolded approach ensures mastery of clauses and complex sentences using developmentally appropriate strategies aligned to Common Core standards.
