This practical resource offers requisite information that teachers must understand when designing pre-algebra instruction for students who struggle in inclusive classrooms, along with sample lessons. These sample lessons are based on evidence-based interventions proven effective for students struggling with mathematics and illustrate what it means to use explicit instruction in designing a pre-algebra lesson plan for students with mathematics difficulties (MD). Among the pre-algebra skills, this book introduces lesson plans selectively on fractions, integers, and expressions and equations. Teachers can use these samples alongside their regular lessons and use them as supplemental instruction or intervention for students with MD outside regular instruction, or as small group instruction within regular classes. While using the lesson plans in this book can be helpful, teachers will achieve even greater results if they carefully review each lesson plan's structure, follow it, and consider how to apply it to their own students.
