1.	Five spelling words are formed by adding the prefix ex to a root that begins with the consonant c. Say those words aloud. Does the letter c have a hard sound or a soft sound? _________________________

3.	In how many words is ex joined to a root that begins with a vowel? _____
4.	Do any of the roots on the spelling list begin with the letter s? _____ with the letter z? _____

Lesson Generalization Only a few words in the English language are formed by adding ex to a soft c or to the letter h. No words are formed by adding ex to the letter s or the letter z. The sound of /s/ or /z/ is made by the x in the prefix ex. The prefix ex is added directly to many roots beginning with vowels. The spelling of the prefix does not change when it is joined to vowels or to the letters c and h.
