Lesson 100
-er/-est
The suffixes -ER and -EST make adjectives comparative
Some adjectives are irregular when adding -ER and -EST (e.g., good, better, best; bad, worse, worst). Many multisyllable adjectives use more/most instead of -ER/-EST (e.g., careful, more careful, most careful; expensive, more expensive, most expensive). Suffix spelling changes are addressed beginning in Lesson 107. The suffix -ER can also be used to change verbs into nouns (e.g., teach -> teacher). This concept is addressed in Lesson 121.

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)

New Concept
Today we learn that the suffixes -ER and -EST can be added to adjectives to make comparisons.
Highlighted words are the ones to show and practice reading — tap one to hear it.
Adjectives are words that give us more information about people, places, and things. For example, in the sentences "I see a red car. I see a blue car," the adjectives red and blue are used to describe the noun car. They give us more information. What kind of car? A red car. A blue car. Morphemes are word parts that change a word's meaning. A suffix is a morpheme we add to the end of a word. We can add the suffixes -ER and -EST to adjectives when we are making comparisons. The suffix -ER is pronounced /er/ like in the word . -ER means more than. For example, in the sentence "Mae is taller than Jaime," taller describes Mae's height by comparing it to Jaime's. The suffix -EST is pronounced /əst/ with the E making a schwa sound, like in the word . -EST means the most. For example, in the sentence "Ty is the fastest person on the team," fastest is an adjective used to describe Ty by comparing him to the rest of the team. It tells us nobody is faster than Ty.
