Scientific Spelling week #9 The Doubling Rule
Look at these words. Hop + ed = hopped Run + er = runner Skip + ing = skipping
Hop + ed = hoppedRun + er = runnerskip + ing = skipping The first column has base words. The second column has suffixes. The third column has derivatives. (Remember that a derivative is a base word plus a suffix or prefix)
Hop + ed = hoppedRun + er = runnerSkip + ing = skipping Let’s see how these base words are the same. What do you see in the final position? Yes the base words end in one consonant.
Hop + ed = hoppedRun + er = runnerSkip + ing = skipping What comes before the final consonant? Yes, there is one vowel. These words are also accented because all one-syllable base words are accented. The base words in the first column end in one vowel, one consonant, and are accented.
Hop + ed = hopped Run + er = runner Skip + ing = skipping Tell me about these suffixes. Are they vowel or consonant suffixes? Yes, they are vowel suffixes.
Hop + ed = hoppedRun + er = runnerSkip + ing = skipping Tell me about the derivatives. How are they the same? Yes, the final consonant of the baseword is doubled
When the base word ends in one vowel, one consonant, and is accented, we double the final consonant before adding a vowel suffix. There are 4 checkpoints: 1. One vowel 2. One final consonant 3. Accent 4. Vowel suffix If any checkpoint is missing, you will not double the final consonant before adding a vowel suffix.
Turn to page 3 in the yellow section of your spelling binder. Now, lets read the information at the top of the page. _______________________________ The Doubling Rule If a base word ends in one vowel, one consonant and one accent, double the final consonant before adding a vowel suffix . Examples: Hop + ed = hopped Run + er = runner Skip + ing = skipping
S.O.S(Save Our Spelling)Procedure • LOOK AND LISTEN Students look at the teacher’s mouth and listen as teacher dictates the word. • ECHO AND THINK Students repeat the word and think about the component parts of the word (sounds, syllables, base words, and affixes.)
3. UNBLEND THE SOUNDS Students unblend the sounds and document them with a sound dot. 4. NAME THE LETTERS AND WRITE Students write the word, naming letters as they write. 5. READ TO CHECK Students read the word they have written and name the letters.
Here are the rest of the words for this week’s spelling list: One Once only These words are irregular words. An irregular word is a word that is spelled in an unexpected way.
Turn to the red section of your spelling book. • Turn to the page with letter “o” • Write the irregualr words and follow the study procedure for irregular words.
