Using Intensive Intervention to Meet the Academic and Behavior Needs of Struggling Learners provided participants with an overview of how principles of intensive intervention may be applied to students with severe and persistent learning needs across reading, mathematics, and behavior. You can download the powerpoints and handouts from their website:
