Fraction Face-Off! with Integrated Fraction-Decimal Component (FM+DM) or Fraction Applications Component (FM+FAPP)

Fraction Face-Off! is a 12-week (36 sessions) fourth-grade intervention focused on fraction magnitude understanding for at-risk students with poor whole-number performance. The intervention is delivered three times per week in 35-minute sessions to dyads (pairs of students). It builds fraction magnitude understanding through benchmark fractions, comparing, ordering, and placing fractions on number lines, using fraction tiles, circles, and number lines as representations. The intervention includes explicit instruction with worked examples, guided practice, fluency-building activities, and systematic cumulative review. Two variants were tested: FM+DM integrates fraction and decimal magnitude instruction (7 minutes per session starting at lesson 7), while FM+FAPP includes fraction word problem applications (7 minutes per session starting at lesson 7). Both variants include a small focus on fraction addition and subtraction (3 of 36 lessons). Tutors require 20 hours of initial training to achieve 95% implementation accuracy before working with students, plus ongoing weekly training meetings.
