Number Line Approach Combined With Cognitive Learning Strategies

This intervention uses a number line-centered approach combined with cognitive learning strategies to teach fraction concepts to sixth graders struggling with mathematics. Delivered in small groups of 3-4 students, the intervention consists of 27 lessons over 6 weeks (approximately 45 minutes per lesson, totaling about 20.25 hours). Each lesson includes warm-up practice, multiplication fact practice, counting fractions aloud, 15-20 minutes of explicit instruction focused on the number line, fast-paced card games for fraction magnitude practice, and independent cool-down worksheets. The intervention covers halves, fourths, eighths, thirds, sixths, and twelfths, teaching students to partition number lines, locate fractions, understand equivalencies, compare magnitudes, and perform basic operations. Instruction incorporates explicit teaching, representational gestures, dual coding (visual and verbal), spaced and interleaved practice, and immediate feedback. Trained research assistants deliver the intervention, requiring prior training (16+ hours) on gestures, feedback strategies, and behavior management.
