Printable Singular & Plural Nouns Worksheet | Grade 3 ELA

This two-page worksheet offers targeted practice for third-grade students on core grammar principles. It sharpens their ability to form and use plural nouns correctly and introduces the fundamental concept of identifying the subject and predicate in a sentence, building a strong foundation for sentence construction and reading comprehension.

• Skill Focus: Singular & Plural Nouns, Subject & Predicate
• Format: 2 pages · 16 problems · Answer key included · PDF
• Best For: Independent practice, formative assessment, grammar review
• Time: 15–25 minutes

This PDF resource contains two distinct sections across two pages. The first page features an eight-item matching task focused on both regular and irregular singular and plural nouns. The second page presents eight sentences where students must identify and label the subject and predicate. An answer key is provided for quick grading.

The worksheet is structured to support a gradual release of responsibility.

• Guided Practice: The first section on plurals acts as a focused warm-up. Teachers can review the concept of singular vs. plural nouns, working through one or two examples like 'child/children' before students complete the matching activity.
• Supported Practice: For the subject and predicate section, the sentences are simple and direct. An instructor can model how to find the verb first and then ask 'who or what is doing the action' to isolate the subject, completing the first two items with the class.
• Independent Practice: Students can then complete the remaining problems independently, applying the rules from both sections. The clear, two-part structure allows for a self-paced workflow, making it an effective tool for solidifying foundational grammar skills.

This worksheet directly addresses Common Core standard CCSS.ELA-LITERACY.L.3.1.b, which requires students to "Form and use regular and irregular plural nouns." The second activity on subjects and predicates serves as a foundational step toward standard CCSS.ELA-LITERACY.L.3.1.i (producing varied sentences). Both standard codes can be copied directly into lesson plans, IEP goals, or district curriculum mapping tools.

This resource is ideal for use after a direct instruction lesson on nouns and sentence parts. Use it as an in-class independent practice activity or as a homework assignment to reinforce the concepts. For a quick formative assessment, observe which irregular plurals (e.g., man/men, child/children) or sentence types cause the most difficulty. The worksheet should take students approximately 15 to 25 minutes to complete.

This worksheet is designed for third-grade students learning core grammar concepts. The clear layout and distinct tasks also make it suitable for fourth-grade students needing review or for English Language Learners acquiring basic sentence structure knowledge. It pairs well with an anchor chart displaying examples of singular/plural nouns and subject/predicate definitions.

This resource provides focused practice on foundational grammar skills essential for early literacy, aligning with CCSS.ELA-LITERACY.L.3.1.b for forming and using plural nouns. Developing automaticity in these grammatical rules frees up cognitive resources for more complex reading and writing tasks. Research consistently shows that explicit instruction in sentence structure improves writing quality and reading comprehension. According to Fisher & Frey (2014), purposeful, standards-aligned practice is a key component of an effective literacy block. By isolating the skills of noun formation and subject-predicate identification in 16 clear problems, this worksheet gives students the repetition needed to build a durable understanding of how words and sentences function, a critical step toward proficient communication. This targeted approach is supported by findings that emphasize moving from part to whole in grammar instruction.
