More research attention and implementation support are needed for mathematics intervention as student achievement in this area continues to fall below desirable levels. Incremental rehearsal is an intervention to help students build reading, vocabulary, and math fluency. Research supports the use of incremental rehearsal for improving math fact fluency. However, this intervention is more complicated than the traditional flashcard intervention. Therefore, an implementation guide is needed to increase its use with students who need to improve math fact fluency. This article will provide step-by-step instructions for implementing incremental rehearsal plus helpful implementation aids such as a chart demonstrating the proper presentation sequence and a treatment integrity checklist.
