This IRIS Star Legacy Module, first in a series of two, overviews data-based individualization and provides information about adaptations for intensifying and individualizing instruction. Developed in collaboration with the IRIS Center and the CEEDAR Center, this resource is designed for individuals who will be implementing intensive interventions (e.g., special education teachers, reading specialists, interventionists).

The purpose of this guide is to provide brief explanations of key practices that can be implemented when working with students in need of intensive intervention in mathematics. Special education instructors, math interventionists, and others working with students who struggle with mathematics may find this guide helpful. Strategies presented in this guide should be used in conjunction with teaching guides developed for specific mathematical concepts.

This collection contains modules that can be used for professional development for middle school leaders, teachers, interventionists and instructional coaches to build their capacity to students who require intervention in mathematics. Basic Facts and Computations. Building Fluency and Conceptual Understanding: Middle School Level Connecting Intervention and Core Instruction. Instructional Strategies to Bridge Skills that Lead to Success: Middle School Level

This module is designed for interventionists, special educators, and general educators to review instructional strategies that students with mathematics difficulties need to be successful in both core instruction and intervention. Students with mathematics difficulties may make progress in intervention but still struggle in core because there is often not a bridge or support to show how the intervention connects to core. This module addresses these needs and identifies how all teachers need to support generalization and build upon mathematics trajectories for students to be successful.

This collection contains modules that can be used for professional development for elementary leaders, teachers, interventionists and instructional coaches to build their capacity to support students who require mathematics intervention.

The purpose of this module is to review how to implement the Early Numeracy Intervention, a validated intervention program that can be used for Tier 2 math intervention, or as an intensive intervention platform within DBI.

The purpose of this module is to focus on the importance of fractions, including the prerequisite skills. Fractions have been cited as a key skill that students need in order to be more successful in advanced mathematics skills, including algebra. Fractions are a necessary skill to be included as part of tiered interventions for students as early as grade 3.

This module is focused on the foundational skills of basic facts and computations across elementary grade levels. This module reviews the math trajectories that lead to long-term success and mastery of facts. Mastery of facts will lead to deeper understanding of facts in order to complete multi-step computations.

Counting and place value are prerequisite skills that are essential for more advanced, multistep mathematics skills. This module focuses on the foundational skills of counting and place value, including common skill areas where students struggle. Instructional skills and case studies are presented to help teachers and interventionists better understand essential skills to include across tiered interventions.
