Intervention Summary

Fusion is a Tier 2 Grade 1 mathematics intervention designed for students at risk in whole-number concepts and skills. The program targets critical whole-number content and is intended to strengthen students' conceptual understanding and procedural fluency in mathematics. The Fusion curriculum consists of 60 lessons, each lasting 30 minutes, delivered over a period of 20 weeks. Each lesson includes the explicit introduction of new content and systematic practice and review in four to five brief, scripted mathematics activities. Lessons use a variety of math models and contain teacher modeling, scaffolded instructional examples, and opportunities for teachers to provide academic feedback based on student responses to individual and group questions.
