Fluency Formula™
About the Intervention
Fluency Formula™ is a supplemental reading curriculum designed to promote reading fluency for first- through sixth-grade students. The program emphasizes automatic word recognition, decoding accuracy, and oral expressiveness as the foundation for building reading fluency. Daily 10- to 15-minute lessons are delivered in classrooms through whole-class, small-group, and individual practice activities. Students use workbooks, read-aloud anthologies, library books, fluency activity cards, and audio CDs. The curriculum encourages at-home practice (20-30 minutes daily) and includes a Fluency Formula™ Assessment System with one-minute grade-level passages and a timer for teachers to assess student fluency. Teachers receive professional development through the Fluency Formula™ Professional Guide and online courses through Scholastic's "Scholastic Red" division.
