1. Grade 3 Unit 1 lesson Review • Lesson Review Short vs. Long Vowel Sounds & • Doubling and Dropping Rules for adding vowel suffixes

2. Vowel suffixes • A suffix is a letter or letters added AFTER the base word to create a new word. • We know a suffix is a VOWEL suffix if the first letter of the suffix is a vowel. • Examples: • - ing • - y • -ed • -er • est

3. Adding vowel suffixes • When you add a vowel suffix to a base word, you MUST know if the final syllable of the base word has a short or long vowel sound. • DOUBLING RULE: When you hear a base word with a short vowel sound, double the final consonant before adding the vowel suffix. • DROPPING RULE: When you hear a base word with a long vowel sound, drop the silent e before adding the vowel suffix.
