The Best Way to Teach the CK Spelling Rule to Make it Stick

The CK Spelling Rule is an easy way to determine when to use the letters ck or the letter k in a word that has the /k/ sound.

Mastering this useful rule makes words that have a /k/ sound easier to spell, eliminates guessing, and reduces dependence on whole-word memorization.

Bumble’s video does a great job of explaining this rule in a fun and entertaining way.

What is the CK Rule?

The CK Rule is this:

CK is only used right after a short vowel.

When the /k/ sound is preceded by a short vowel, use ck.

Examples: back, neck, block, and stick

Also: duck, cracker, bucket, necktie, and Mack

It is when the /k/ sound is preceded by a consonant, a long vowel, or a vowel team that students should use a k for the /k/ sound, as in bank, like, and look.

Here are examples of the types of words that use the letter k for the /k/ sound.

1. Use a k when the /k/ sound is preceded by a consonant.
• Examples: mark, silk, tank, walk, Frank
2. Use a k when the /k/ sound is preceded by a long vowel sound.
• Examples: hike, croak, make, peak, Luke
3. Use a k when the /k/ sound is preceded by a vowel team.
• Examples: book, seek, peak, spook, Brook
