Aligned CCSS RF.K.3 Digraphs and Blends Grade K Worksheet

This Kindergarten phonics worksheet helps students master the critical distinction between consonant blends and digraphs. By analyzing 10 specific word examples, learners develop the phonemic awareness necessary to decode complex words. The student outcome is the ability to identify whether letter combinations represent a single sound or two distinct blended sounds.

At a Glance

• Grade: Kindergarten · Subject: ELA Phonics
• Standard: CCSS.ELA-LITERACY.RF.K.3 — Know and apply grade-level phonics and word analysis skills in decoding words
• Skill Focus: Digraphs vs. Blends
• Format: 3 pages · 10 problems · Answer key included · PDF

• Time: 15–20 minutes

This 3-page PDF contains 10 structured multiple-choice questions. Each question is paired with a high-quality visual anchor—such as a whale, a ring, or a dress—to provide context for the target word. The first half of the quiz requires students to categorize the sound structure, while the second half asks them to isolate the specific letter combination, such as the "th" in the word "think."

The assessment is designed to provide clear evidence of student progress toward phonics mastery. Tasks 1–6 evaluate the ability to categorize sounds, while tasks 7–10 measure the ability to isolate phonemes. Teachers can use the included rubric to categorize performance: Approaching (1-5 correct), Meeting (6-8 correct), or Exceeding (9-10 correct). These scores can be entered directly into gradebooks or used to update IEP progress notes for foundational literacy goals.

Primary standard CCSS.ELA-LITERACY.RF.K.3: "Know and apply grade-level phonics and word analysis skills in decoding words." This resource specifically targets the sub-skill of recognizing that some letter combinations function as a single phoneme (digraphs) while others maintain individual sounds (blends). Both standard codes can be copied directly into lesson plans, IEP goals, or district curriculum mapping tools.

Use this worksheet as a summative exit ticket after a week of direct instruction on digraphs and blends. During the activity, observe if students are sounding out the words or relying solely on the pictures; this provides a formative-assessment observation tip for identifying students who need more phonemic isolation practice. Expected completion time is 15 to 20 minutes.

This resource is ideal for Kindergarten students, first-grade RTI groups, and English Language Learners (ELLs) who need visual support to connect vocabulary with phonetic structures. It pairs naturally with an anchor chart displaying common digraphs like /sh/, /ch/, and /th/ alongside common blends like /fl/ and /dr/.

According to the RAND AIRS 2024 report on foundational literacy, explicit instruction in phoneme-grapheme mapping is essential for early reading success. This worksheet aligns with evidence-based practices by requiring students to distinguish between digraphs (one sound) and blends (two sounds), a key milestone in the CCSS.ELA-LITERACY.RF.K.3 progression. Research indicates that using visual anchors alongside multiple-choice identification helps solidify the orthographic mapping process for young learners. By isolating the specific letter combinations in words like "crash" and "flash," students move from simple sound recognition to active decoding. This structured approach ensures that Kindergarteners develop the necessary sub-skills to transition from emergent to fluent reading. The 10-task format provides sufficient data points for educators to determine if a student has reached mastery or requires targeted intervention in specific phonics domains.
