The document describes using a Promethean Board and associated technology to help students learn to identify and pronounce r-controlled vowels in one-syllable words. The teacher models sorting words into categories of "-ar" and "-or" words on the board, then students take turns using the pen to drag words out of a hat and place them in the correct columns. Using the Promethean Board engages the students and helps them learn the target sounds faster than alternative methods while also familiarizing them with educational technology.
