Double It or Choose CK

Overview

Students revisit two spelling patterns through explicit teaching and dictation: the 1-1-1 doubling rule and the use of c or ck for the /k/ sound. They explain why a spelling choice is correct, then apply the rules in short, meaningful sentences.

Learning intentions

• We are learning to apply the 1-1-1 rule when adding a vowel suffix.
• We are learning to choose c or ck for the /k/ sound.
• We are learning to listen carefully, spell accurately, and explain our choices.
• We are learning to check that our writing is clear for a reader.

Success criteria

• I can identify one syllable, one short vowel, and one final consonant in a base word.
• I can double the final consonant before adding a vowel suffix when the 1-1-1 rule applies.
• I can use ck after a short vowel at the end of a word and c in other common positions.
• I can correct my spelling and explain the rule I used.

Curriculum links

• Writing to inform — introducing a topic clearly and grouping related information logically.
• Audience, purpose, and language choice — justifying choices about content included or left out.
• Planning and drafting — building sufficient knowledge before planning and writing.
• Transcription skills — accurate spelling supports fluent composition and meaning.

Lesson structure (20 minutes)

1. 0–3 min · Hook and recall. Teacher displays the question “Why is it running, but not runing?” using the opening question slide and invites each student to make a quick prediction. Students discuss what changes when a suffix is added and share one idea.

2. 3–7 min · Teach the 1-1-1 rule. Teacher uses the 1-1-1 rule slides to model run + ing = running, hop + ed = hopped, and jump + ed = jumped. Explain that a one-syllable base word ending in one short vowel followed by one consonant doubles the final consonant before a vowel suffix; students identify the short vowel, final consonant, and suffix in each example.

3. 7–10 min · Teach c and ck. Teacher presents the c and ck comparison slide and models back, neck, and pick, contrasting these with music, picnic, and public. State the useful spelling pattern: ck commonly comes after a single short vowel at the end of a word, while c is used in many other positions for /k/; students sort the examples orally and justify one choice.

4. 10–16 min · Guided dictation. Teacher distributes the spelling and dictation worksheet and reads each sentence from the dictation instructions and sentences first for meaning, then in short phrases, and finally once for checking. Students write independently, reread each sentence, and underline words where they applied a rule.

Dictate these sentences:

• The rabbit is running across the back garden.
• I hopped over the thick crack in the path.
• The music stopped when the picnic bell rang.
• We picked a black backpack for the camping trip.

Remind students that running, hopped, and stopped show the 1-1-1 rule, while back, thick, crack, picked, black, and backpack show ck after a short vowel. In music and picnic, the /k/ sound is written with c.

5. 16–19 min · Check and explain. Teacher reveals the correct sentences on the answer and explanation slides and asks students to compare carefully, correcting in a different colour on the worksheet. Each student explains one corrected word using the language “I used ___ because ___.”

6. 19–20 min · Exit response. Teacher uses the final check slide to give two quick items: “Write plan + ing” and “Complete bla__.” Students write planning and black, then state the rule for one answer aloud or on the worksheet.

Resources

• the complete spelling mini-deck
• the spelling and dictation worksheet
• Pencils and a different-coloured editing pen
• Whiteboard and marker
• Optional individual sound-mapping counters or fingers for identifying phonemes

Assessment

• Listen during modelling and sorting for accurate identification of short vowels, final consonants, and suffixes.
• During dictation, note whether students apply doubling in running, hopped, and stopped, and select c or ck appropriately.
• Use the final two-item check and each student’s explanation to identify who needs further practice with doubling or /k/ spellings.

Differentiation

• Support students by saying the base word and suffix separately, then stretching the word aloud; provide the prompts “short vowel?”, “one final consonant?”, and “vowel suffix?”.
• Allow students to cover the answer slide while writing, and provide a small word bank containing run, hop, stop, back, thick, crack, music, picnic if spelling fluency is a barrier.
• For students needing language or processing support, read each sentence twice, clarify vocabulary such as crack and picnic, and give extra time to reread.
• Extend confident students by asking them to write a new sentence containing one 1-1-1 word and two /k/ words, then explain why each spelling choice helps the reader understand the sentence.
