After writing Brick & Stick: Branching Out, a second grade teacher told me she loves to teach the -ck rule to her students using our books.
After teaching for over 3 decades I did not know the rule.
The Rule – if the word has a long vowel sound or an extra consonant then you only use a k. If it has a short vowel sound then you need to use ck.
I found this fun activity. For more details, check out this site.
Now that you know this slick trick, have a fantastic day!
(Wait, what is the rule for fantastic????)
