The drop e rule

When does the rule apply?

The silent e has one job in a word like hope: it reaches back over the p and makes the o long. A vowel suffix can do that job by itself. In "hoping", the i of -ing follows the single p, so the o stays long without the e. Keeping both would give "hopeing", with an extra vowel nobody pronounces. A consonant suffix cannot reach back, so the e stays: hopeful, lately, movement.

How do you teach it?

Teach it right after students read vowel-consonant-e words fluently and know -ing and -ed. Write a base word, cover the e with your finger, add the suffix and read it. Students see the vowel stay long. Then try it with -ful and watch the vowel turn short ("hopful"), which shows why the e has to stay.

"We're adding -ing to 'skate'. Does -ing start with a vowel? Yes, i. The i will keep the a long, so we don't need the e anymore. Drop it: skating. Now 'safe' plus -ly. -ly starts with l, a consonant. The e stays: safely."

What is the common error, and the fix?

Students write "makeing", "hopeing" and "niceest". Later they swing the other way and drop the e before consonant suffixes: "hopful", "lovly". The fix is to look at the first letter of the suffix every time. Vowel: drop the e. Consonant: keep it.

Sort it: a hands-on activity

Make base-and-suffix cards (bake + ing, care + ful, close + er, use + less, wide + est). Students sort into "drop the e" and "keep the e", write the new word and read it aloud to check the vowel sound.
