Double and Choose

Overview

Students learn to apply the 1-1-1 doubling rule when adding a vowel suffix and choose ck or c to represent the /k/ sound. They use spoken, word-building and dictation activities to explain their choices and spell words accurately.

Learning intentions

• WALT identify the features of a 1-1-1 word.
• WALT apply the doubling rule before adding a suffix beginning with a vowel.
• WALT choose ck or c for the /k/ sound at the end of a word.
• WALT use spelling rules when writing dictated sentences.

Success criteria

• I can explain that 1-1-1 means one syllable, one short vowel and one final consonant.
• I can double the final consonant before adding a vowel suffix, as in run → running.
• I can use ck after a short vowel at the end of a one-syllable word, as in back.
• I can explain why I chose c or ck and spell dictated sentences accurately.

Lesson structure (30 minutes)

1. 0–4 min · Hook and retrieval. Teacher opens with the hook and retrieval slides, displaying hop, hope, hop + ing and asking, “Why does one word change before the ending is added?” Students read the words aloud, identify the vowel sounds and share what they notice. Briefly explain that today’s rules help writers make accurate spelling choices.

2. 4–10 min · Teach the two rules. Teacher uses the rule explanation slides to model the following.

1-1-1 doubling rule: If a word has one syllable, ends in one short vowel followed by one consonant, double the final consonant before adding a suffix beginning with a vowel. Examples: run → running, shop → shopped, plan → planning. Do not double when the final consonant is already doubled, when there are two consonants after the vowel, or when the vowel is not short: jump → jumping, rain → raining.

c or ck: At the end of a one-syllable word, use ck after a short vowel: back, neck, sick, rock, duck. Use c when the /k/ sound follows another consonant or is not immediately after a short vowel: milk, desk, picnic. Students repeat the examples and explain the sound immediately before ck or c.

3. 10–16 min · Guided word investigation. Teacher displays the guided sorting slides and says one word at a time: grab, hope, swim, jump, stick, milk, rock, picnic. Students take turns deciding whether each word is a 1-1-1 word, whether its final consonant should double before -ing, or whether its /k/ sound needs c or ck. Record responses on the board in two headings: “Double before a vowel suffix” and “Use c or ck”. Ask, “What evidence from the word supports your decision?” Correct misconceptions immediately, especially confusing the short vowel rule with the doubling rule.

4. 16–23 min · Independent spelling practice. Distribute the doubling and c-or-ck practice worksheet. Students complete a short set of tasks: underline the short vowel in 1-1-1 words; rewrite words with -ing or -ed; choose c or ck; and write a brief reason for two answers. Suggested words include stop, admit, rub, begin, tap, back, neck, milk, picnic and rock. Teacher works alongside the students, prompting them to say the word, identify its syllables and vowel sound, and apply the rule rather than guessing.

5. 23–28 min · Dictation. Teacher displays the dictation instructions and sentence slides, but covers the sentences while dictating. Read each sentence twice, allowing thinking time between readings. Students write independently, then reread their work.

• “The rabbit was hopping across the rock.”
• “I packed a snack before the picnic.”
• “The duck was swimming in the pond.”
• “We stopped at the desk to check the list.”

Students compare their spelling with a partner, then use the rules to check hopping, packed, snack, picnic, duck, swimming, stopped and check. Invite students to explain one correction. Note that check uses ck because /k/ follows the short vowel e at the end of a one-syllable word.

6. 28–30 min · Plenary and exit check. Teacher returns to the plenary slides and asks each student to complete two oral statements: “I double the final consonant when…” and “I use ck after…”. Students complete the final two items on the worksheet: sit + ing and music or musick? They must write the correct answer and one rule-based explanation. Collect responses to identify who can apply each rule independently.

Resources

• the complete spelling rules and practice deck
• the doubling and c-or-ck practice worksheet
• Whiteboard and markers
• Pencils and erasers
• Exercise books or lined paper
• Prepared dictation sentences
• Small individual word cards or mini-whiteboards

Assessment

• Listen to students explain their decisions during guided sorting; record whether they identify the short vowel, syllable count and final consonant.
• Check the worksheet for accurate application of both rules, not just correct answers.
• Use the dictation and exit check to identify whether errors arise from hearing the sound, recalling the rule or recording the spelling.

Differentiation

• Support students by using counters or finger taps to count syllables, highlighting the short vowel, and providing the sentence frame: “I chose ___ because the word has ___.”
• During dictation, repeat each sentence in meaningful chunks and allow students to quietly rehearse difficult words before writing.
• Provide an individual rule card showing “short vowel + final consonant = double before a vowel suffix” and “short vowel + /k/ at word end = ck”.
• Extend confident students by asking them to generate a new word for each rule and explain why helping, raining, traffic and basket do not follow the target pattern.
