Help first-grade students master the foundational skill of identifying root words within common inflectional forms. This worksheet provides structured practice in peeling back suffixes like -ing and -ed to reveal the core base word. Students build essential decoding and vocabulary skills through 20 targeted problems that promote linguistic awareness and reading fluency.
At a Glance
- Grade: 1 · Subject: English Language Arts
- Standard:
CCSS.ELA-LITERACY.L.1.4.C— Identify frequently occurring root words and their inflectional forms in simple text- Skill Focus: Root Words and Base Words
- Format: 3 pages · 20 problems · Answer key included · PDF
- Best For: Independent practice and small group literacy centers
- Time: 15–25 minutes
This three-page PDF offers 20 tasks across three sections. Pages one and two focus on word-to-word transformations, where students extract base words from verbs with -ing and -ed endings. Page three challenges students to identify roots of bolded terms within sentences. A full answer key is included.
Skill Progression
- Guided Practice: The first six problems provide a clear visual example (jumped to jump) to establish the pattern for isolating suffixes from common action words.
- Supported Practice: Ten additional word-level tasks on the second page reinforce the concept across a wider variety of verbs, ensuring students recognize the consistency of root words.
- Independent Practice: The final four sentence-based problems require students to apply their knowledge in a realistic reading context, moving from isolated words to functional application.
This sequence follows the gradual-release model, transitioning from simple recognition to contextual identification using an I Do, We Do, You Do approach.
Standards Alignment
Strictly aligned to CCSS.ELA-LITERACY.L.1.4.C, this resource helps students identify frequently occurring root words and their inflectional forms (e.g., "looked," "looking," "looks" sharing a base). It also supports CCSS.ELA-LITERACY.RF.1.3.F for reading words with inflectional endings. Standard codes can be used directly for lesson plans or IEP goals.
How to Use It
Use during direct instruction on suffixes or for independent practice. After modeling how to remove endings to find basic words, distribute for desk work. Observe students on sentence-level tasks for formative assessment of lexical processing. Expected completion time: 15-25 minutes.
Who It's For
Designed for first-grade students beginning word study and morphology, this activity benefits early readers struggling with multi-syllabic words or inflectional endings. It pairs well with a classroom anchor chart on suffixes or leveled reading passages for active practice.
Research underscores the importance of early morphology exposure for reading comprehension and vocabulary growth. By Grade 1, students need to understand how base words and suffixes interact. This worksheet directly supports CCSS.ELA-LITERACY.L.1.4.C, offering 20 practice opportunities for "un-packing" words. Scaffolded practice, progressing from isolated words to sentences, aids internalization for active reading, providing a stable foundation for complex texts.
