Lesson 4

Adding -ed and -ing

Spelling Focus: Here are four things to remember when adding -ed and -ing:

Some base words are not changed: happen, happened, happening
In words that end with consonant-e, the e is dropped: dance, danced, dancing
In words that end in y, the y is changed to i when adding -ed, but kept when adding -ing: study, studied, studying
In one-syllable words that end with consonant-vowel-consonant, the final consonant is doubled: stop, stopped, stopping
