This article provides co-teachers with four planning tips to improve implementation of the practices they adopt. The planning tips are organized using the acronym FIRST: (a) monitor Fidelity of implementation of the adopted practices, (b) Integrate the practices into daily content-area instruction and across the year, (c) determine the Roles of each co-teacher when planning for and implementing instruction in the adopted practices, and (d) consider specific guidelines to Select Texts for each literacy-focused lesson.
