Printable -ug and -ung Word Sort Worksheet | Grade 1-3

This printable word sort worksheet helps Grade 1-3 students master the phonics patterns for the -ug and -ung word families. By categorizing ten specific words, learners strengthen their phonemic awareness and decoding speed. This essential practice ensures students can distinguish between similar ending sounds, a critical step toward fluent reading and accurate spelling in primary grades.

This worksheet features a clean, two-column layout. Students sort ten decodable words—including drug, clung, snug, and swung—into the correct "-ug" or "-ung" category. Available in printable and interactive formats, it works for any classroom setting. A comprehensive answer key is included to facilitate quick grading or student self-correction.

• Guided practice: Teachers begin with a choral read of the word bank.
• Supported practice: Students then sort the first four words (drug, clung, snug, slung) with teacher support.
• Independent practice: Finally, learners complete the remaining six sorts independently, demonstrating mastery of the phonics patterns.

This gradual-release approach ensures students build confidence before moving into independent application of their phonological skills.

The primary focus is CCSS.ELA-LITERACY.RF.1.3: "Know and apply grade-level phonics and word analysis skills in decoding words." Specifically, it targets decoding one-syllable words by identifying common rimes. This standard code can be copied directly into lesson plans, IEP goals, or district curriculum mapping tools to ensure instructional alignment with state and national expectations.

Use this worksheet during small-group literacy blocks as a quick formative assessment. Observe whether students are reading the whole word or simply matching letters; this distinction helps identify those needing blending support. It also serves as an excellent bell-ringer or warm-up activity during your phonics block, typically taking students 10 to 15 minutes to complete.

This resource is for first graders beginning word families, or older students needing remedial support. It is particularly effective for English Language Learners (ELLs) struggling with nasalized endings like "-ung." Pair this with a short passage containing these word families or a classroom anchor chart for maximum instructional impact and student growth.

Mastering word families like -ug and -ung is a foundational component of the "Words Their Way" approach to spelling and phonics. Research by Fisher & Frey (2014) highlights that systematic word sorting allows students to discover the regularities of the English language through hands-on manipulation. According to the RAND AIRS 2024 report on primary literacy, students who engage in targeted phonics practice with consistent word patterns show significantly higher retention rates in decoding accuracy. This Grade 1-3 worksheet provides the structured repetition necessary for students to move from phonemic awareness to automaticity. By isolating the -ug and -ung endings, the activity minimizes cognitive load while maximizing the student's ability to recognize phonological rimes. The inclusion of CCSS.ELA-LITERACY.RF.1.3 ensures that this practice is not just busy work but a direct path toward meeting national literacy benchmarks for one-syllable word decoding.
