Compound Predicates Worksheet | Grade 3 ELA Printable

This Grade 3 grammar worksheet provides targeted practice with compound predicates, helping students combine simple sentences to eliminate repetitive writing. By identifying shared subjects and joining verbs with coordinating conjunctions, young writers construct dynamic sentences that improve reading fluency and express complex actions clearly.

What's Inside

This two-page resource features 10 structured exercises designed to reinforce sentence combining. The worksheet begins with clear definitions and a worked example demonstrating how two sentences with the same subject merge into one sentence with a compound predicate. Students match verbs to subjects, combine simple sentences using connecting words, and rewrite repetitive paragraphs into concise prose. A complete answer key is included for quick grading.

Skill Progression

The worksheet follows a structured sequence to build student confidence through intentional scaffolding:

• Guided practice: The first 3 problems provide sentence frames where students select and insert the correct coordinating conjunction to join two underlined verbs.
• Supported practice: The next 4 problems require students to identify separate sentences with identical subjects and rewrite them as a single sentence with a compound predicate.
• Independent practice: The final 3 problems challenge students to evaluate a repetitive passage and rewrite it independently by creating compound predicates.

This gradual-release model ensures a smooth transition from I Do, We Do, You Do, allowing students to achieve mastery.

Standards Alignment

This worksheet is directly aligned to CCSS.ELA-LITERACY.L.3.1.I, which requires students to produce simple, compound, and complex sentences. It also supports CCSS.ELA-LITERACY.L.3.3.A by encouraging students to choose words and phrases for effect. Both standard codes can be copied directly into lesson plans, IEP goals, or district curriculum mapping tools.

How to Use It

Teachers can deploy this worksheet during independent practice following direct instruction, or as a targeted intervention station. As a formative assessment observation tip, watch whether students correctly drop the redundant subject pronoun when combining sentences; retaining the second subject indicates a need to review basic subject-verb relationships. Expected completion time ranges from 15 to 20 minutes.

Who It's For

This resource is designed for third-grade general education students, but serves as an excellent remedial tool for fourth graders needing reinforcement. For English Language Learners, initial sentence frames provide necessary structural support. This worksheet pairs naturally with an anchor chart displaying coordinating conjunctions or a mentor text mini-lesson.

Mastering compound predicates is essential for developing syntactic maturity in elementary writers. Aligned with CCSS.ELA-LITERACY.L.3.1.I, this worksheet focuses on the plain-English skill of combining sentences with shared subjects to produce clear, fluent writing. According to Fisher & Frey (2014), structured gradual-release frameworks provide the necessary scaffolding for students to internalize complex grammatical structures before applying them independently in their own compositions. Explicit instruction in sentence combining directly correlates with improved reading comprehension and writing quality, as students learn to construct more sophisticated syntactic patterns. By transitioning students from guided sentence frames to independent paragraph revision, this resource bridges the gap between isolated grammar drills and authentic writing application. This systematic approach ensures that third-grade students build the foundational sentence-construction habits required for advanced literacy success.
