This Grade 1 English Language Arts worksheet helps students master identifying root words and common suffixes like -s, -es, -ing, and -ed. Breaking words into base components builds morphological awareness, essential for reading fluency and revealing original word meanings.
At a Glance
- Grade: 1 · Subject: ELA
- Standard:
CCSS.ELA-LITERACY.L.1.4.C— Identify frequently occurring root words and their inflectional forms during reading- Skill Focus: Root Words and Suffixes (-s, -es, -ing, -ed)
- Format: 4 pages · 22 problems · Answer key included · PDF
- Best For: Independent literacy center or morning work
- Time: 20–30 minutes
This 4-page PDF resource offers structured practice across four sections. It includes a clear suffix definition, a suffix bank, 12 tabular word analysis tasks, 6 sentence completion exercises, and 4 matching pairs. A full answer key is included for rapid grading or self-check.
Skill Progression
- Guided Practice: Part 1 uses a suffix bank and table to identify endings and isolate root words in 12 examples.
- Supported Practice: Part 3 applies knowledge to sentence completion, choosing correct suffixes based on grammatical context.
- Independent Practice: Part 4 requires matching full words to roots without prompts, demonstrating concept mastery.
This progression ensures students move from recognition to application within a single session, following the gradual-release model.
Standards Alignment
Primary focus is CCSS.ELA-LITERACY.L.1.4.C, requiring students to identify frequently occurring root words and inflectional forms. This worksheet specifically targets how suffixes change word functions while maintaining core meaning. Standard codes can be used in lesson plans, IEP goals, or curriculum mapping.
How to Use It
Deploy this resource during independent practice after introducing suffixes as word endings. Use the first two pages for initial understanding of root plus suffix structure. The sentence completion page serves as formative assessment for applying knowledge to functional text. Observe for spelling changes in words like boxes or wishes during completion.
Who It's For
Designed for Grade 1 students developing early literacy skills. Highly effective for English Language Learners (ELL) needing explicit morphology instruction. Structured tables and word banks provide scaffolding for students with reading IEPs. Pair with a suffix anchor chart or Root Word Tree display for cohesive learning.
Morphological awareness predicts reading comprehension success (NAEP frameworks). Research by Fisher & Frey (2014) emphasizes explicit instruction in word parts via gradual release, integrated into this 4-page set. Teaching first-grade students to isolate root words and understand inflectional endings like -ed and -ing builds cognitive pathways for decoding multisyllabic words in complex texts. This worksheet provides the high-repetition, structured practice recommended by NAEP to ensure students transition from learning to read to reading to learn. Mastery of CCSS.ELA-LITERACY.L.1.4.C ensures learners navigate lexical demands of early elementary texts and build robust vocabulary.
