In this section, students are introduced to the three most common r-controlled vowel spellings: ER, AR, and OR. They will learn what an r-controlled syllable is, review a keyword for each spelling, and begin building awareness of how the vowel sound is changed when followed by the letter r. This foundation will support the reading, spelling, and writing activities that follow.
