Grade 1 Suffixes — Printable No-Prep Worksheet

This ready-to-use worksheet helps first-grade students practice identifying and using common suffixes. Students will add inflectional endings like -ing, -ed, and -s to familiar root words, building a foundational understanding of how words change. This targeted practice strengthens both spelling and vocabulary in a clear, straightforward format.

Standards Alignment

This worksheet aligns with CCSS.ELA-LITERACY.L.1.4.c, which requires students to identify root words and their inflectional forms (e.g., looks, looked, looking). The activity provides direct practice by having students add suffixes to root words. The standard code can be copied directly into lesson plans, IEP goals, or curriculum maps.

How to Use It

Use this resource as independent practice after a mini-lesson on suffixes. It works well in a literacy center for pair work. For formative assessment, observe if students can correctly match the suffix to the base word. The task should take about 10-15 minutes.

Who It's For

Ideal for first-grade students learning about affixes, this worksheet also serves as review for second graders or intervention for older students. The simple format is accessible. Pair this with a word-sorting anchor chart to categorize words by their endings.

Targeted practice with word parts is a cornerstone of early literacy instruction, directly supporting the decoding skills outlined in CCSS.ELA-LITERACY.L.1.4.c. By manipulating suffixes, students move beyond memorization and begin to understand the morphological system of English. This ability to analyze word structure is a key predictor of reading comprehension. Research emphasizes that explicit instruction in morphology significantly improves vocabulary acquisition and reading fluency. According to Fisher & Frey (2014), a deep understanding of how words are formed gives students the tools to deconstruct unfamiliar words and construct new ones. This worksheet provides a practical application of that principle, giving young learners hands-on experience with root words and their common inflectional forms, a foundational skill for all future reading and writing tasks.
