About the Intervention
Fraction Face-Off! is a 12-week fraction intervention program for at-risk fourth graders, delivered in small groups of two students, three times per week for 35 minutes per session. The program emphasizes the measurement interpretation of fractions using number lines (70% of representation emphasis), fraction tiles, and fraction circles, while also addressing part-whole understanding, comparing and ordering fractions, equivalencies, and adding/subtracting fractions. Each session includes six activities: Word-Problem Warm-Up (7 min), Training (8-12 min introducing concepts with manipulatives), The Relay (8-12 min group work), Sprint (2 min speeded practice), The Individual Contest (5 min independent practice), and The Scoreboard (1 min feedback). Tutors were full- or part-time research grant employees (some licensed teachers, most not) who received initial week-long training plus bi-weekly follow-up sessions. The program includes a behavioral management system with timers, checkmarks, and a Fraction Store where students spend earnings on prizes.
