2 pages in this set
Free printable fill in the missing letters (pig) worksheet for 1st grade students. Part of our letter sounds spelling collection. Aligned to Common Core standards.
How do I use this worksheet?
Begin with a shared reading or oral warm-up that highlights letter sounds so students hear and see the skill in context before practicing it independently. As students work through the worksheet, encourage them to say answers aloud first and then write them, especially for phonics-based tasks. After completing the worksheet, use one or two examples from the page to start a discussion: "Where else have you seen this in your reading?" These letter sounds worksheets are ideal for use during small group reading time, as independent center work, or as a homework activity.
What students will practice
- Students will identify and apply letter sounds knowledge to decode and comprehend grade-level text.
- Students will recognize patterns and rules related to letter sounds in spoken and written language.
- Students will build fluency and confidence with letter sounds through guided and independent practice.

FAQ
How do I use this letter sounds worksheet?โ
Begin with a shared reading or oral warm-up that highlights letter sounds so students hear and see the skill in context before practicing it independently. As students work through the worksheet, encourage them to say answers aloud first and then write them, especially for phonics-based tasks. After completing the worksheet, use one or two examples from the page to start a discussion: "Where else have you seen this in your reading?" These letter sounds worksheets are ideal for use during small group reading time, as independent center work, or as a homework activity.
What does this worksheet teach?โ
These letter sounds worksheets for 1st grade give students focused practice with one of the key skills in early literacy. Students read, identify, and respond to letter sounds through a variety of activities designed for their grade level. Our spelling worksheets build both decoding skills and reading comprehension, helping students connect what they practice on paper to the books they read every day. Regular practice with letter sounds strengthens the reading skills that 1st grade students need to become confident, independent readers.
What grade level is this letter sounds worksheet for?โ
"Fill in the missing letters - Pig" is written for 1st Grade (Ages 6-7), and it covers Common Core RF.1.3.G. If your little one is a year younger but already steady on spelling, the page still works. You may just need to read the instructions out loud. And if they are older and letter sounds never quite stuck, this is a short review rather than busywork.
Can I use this letter sounds worksheet for homeschool or classroom?โ
Yes, both. We made it for 1st Grade spelling, and the page works the same whether it lands on a kitchen table or a center rotation. At home, most families go through it together and talk the answers out loud, and that talking is where most of the learning happens with letter sounds. In class it runs well as independent work while you pull a small group. Print one copy or thirty, whichever the day needs.
How does letter-sound knowledge support spelling in 1st grade?โ
Accurate spelling requires students to segment a spoken word into individual phonemes and match each phoneme to the correct grapheme - a process that begins with secure knowledge of individual letter-sound correspondences.
What letter sounds should be fully mastered by the start of 1st grade?โ
Students entering 1st grade should know the sounds of all 26 single letters - both consonants and vowels - and begin working on digraphs, blends, and vowel teams throughout the 1st grade year.
How can letter-sounds spelling worksheets help identify students who need intervention?โ
Patterns of errors on letter-sounds worksheets (consistent vowel confusion, systematic consonant substitutions) help teachers identify specific phonological gaps and target intervention to the precise skill that needs development.
What spelling skills should a first grader have?โ
First graders should spell CVC words correctly (cat, dog, run), use common spelling patterns (CVCe for long vowels: make, bike, home), and apply phonics knowledge to spell unfamiliar words (CCSS L.1.2d, L.1.2e). They should also spell high-frequency sight words correctly (the, was, said, they). By year's end, most first graders can spell 50 to 100 words conventionally and use invented spelling that is increasingly phonetically accurate for unknown words. Worksheets that target specific spelling patterns (short a words, long vowel words, digraph words) provide focused practice. Spelling instruction should connect to phonics and reading, not exist in isolation. Words children learn to spell should appear in the texts they are reading, creating a reinforcing cycle between decoding and encoding.
How do you teach spelling to first graders?โ
Use a word study approach that connects spelling to phonics patterns. Group words by their spelling pattern (short a words: cat, hat, map, fan) and teach the pattern explicitly. Have students sort words, build them with letter tiles, write them, and use them in sentences. The "look, say, cover, write, check" method builds visual memory for tricky words. Worksheets that include word sorts, fill-in-the-blank with spelling words, and sentence dictation provide varied practice. Avoid random word lists that have no phonetic connection to each other. Research from Bear and Templeton shows that word study approaches produce stronger spelling outcomes than rote memorization because students learn transferable patterns. Test spelling through writing activities, not just isolated word lists, to see if children apply their spelling knowledge in context.
Should I correct my first grader's invented spelling?โ
Encourage invented spelling during creative writing (journals, stories) because it keeps children writing fluently without stopping to ask for correct spelling. However, expect conventional spelling for words that have been explicitly taught (sight words, pattern words from spelling lessons). The balance shifts throughout first grade: early in the year, celebrate phonetically reasonable attempts. By spring, hold students accountable for the patterns and words they have studied. Worksheets that focus on specific spelling patterns should require correct spelling, while open-ended writing tasks can be more forgiving. When correcting, point out what the child did right first ("You heard the /k/ and /t/ sounds in 'cat,' and you just need to add the 'a' in the middle"). This approach maintains confidence while building accuracy.
