Doubling and C or CK Rules
The sailing club is preparing its race-day log. Help Ruben, Isla and Tui spell each word correctly. Use the rules: double a final consonant before a vowel suffix when a word ends in one short vowel followed by one consonant; after a short vowel at the end of a one-syllable word, use ck for the /k/ sound.
Spot the pattern
1.At the sailing club, the log lists six actions: dock, sail, plan, tap, picnic and race. Which two words have one syllable, one short vowel and one final consonant? Write both words.
2.Ruben adds -ing to tap. Choose the correct spelling for the log.
- taping
- tapping
- tappping
3.Isla adds -ed to the word admit. Write the correctly spelled past-tense word.
4.Tui writes, “The crew is rubing down the wet deck.” Rewrite the sentence with the spelling corrected.
