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

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

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.

DOUBLE OR DROP? bone + y = bony cut + ing = cutting DOUBLING RULE WORDS DROPPING RULE WORDS Base Word w/ Short Vowel Sound cut + ing = cutting shop + er = shopper big + er = bigger hop + ing = hopping (Doubling the final consonant protects the vowel, so it keeps a short vowel sound). Base Word w/ Long Vowel Sound bone + y = bony grade + ed = graded shine + ing = shining hope + ing = hoping
