Lesson 108
Doubling Rule -er, -est
Spelling change with -ER and -EST
The concept of a doubled consonant representing a single sound was introduced in Lesson 42. Remember, the suffixes -ER and -EST help us make comparisons. -ER means more and -EST means the most.

Warm Up Our Ears
Say the sounds; students blend them into a word. Then say a word; students break it apart.
Blend it (teacher says sounds → you say word)
Break it (I say word → you say sounds)
Sound Drills
Full-screen cards for the class. Tap a card to check the answer, or press Hear the words to hear the example words read aloud.
👂 Listen & Spell — teacher list (13 sounds)
Say each sound; students write the spelling(s). Read straight from this list.

Blending Drill
Change one part at a time and read the new word.
New Concept
Today we learn how the doubling rule applies when we add -ER and -EST to words with one vowel and one final consonant.
Highlighted words are the ones to show and practice reading — tap one to hear it.
We learned that when we add the suffixes -ED and -ING to words with one vowel and one final consonant, we need to double the final consonant before we add the ending. We follow the same pattern when adding the suffixes -ER and -EST to words with one vowel and one final consonant. For example, the word has one vowel (i) and one final consonant (g). To turn big into bigger or biggest we need to add another g before we add the -ER or -EST ending.
Doubling Rule -er, -est
When a one-syllable word has one vowel and one final consonant, we double the final consonant before adding -ER or -EST.
