OER, a part of the global open content movement, are shared teaching, learning, and research resources available under legally recognized open licenses—free for people to reuse, revise, remix, and redistribute. Why are OER important? High-quality OER can save teachers significant time and effort on resource development and advance student learning inside and outside the classroom. Further, open sharing of resources has the potential to fuel collaboration, encourage the improvement of available materials, and aid in the dissemination of best practices.

With all the promise of OER, some challenges remain. One of these is assuring the quality of resources. Achieve's Open Educational Resources includes a set of downloadable rubrics that can help districts, teachers, and other users evaluate OER for quality and determine the level of alignment to the Common Core State Standards (CCSS). Additional rubrics for evaluating OER quality have been collected as part of the Washington OER Project. It's worth noting that many of the larger repositories for OER will include copyright information, and their materials will typically adhere to some established criteria.
Exploring free lesson planning resources can be overwhelming. Some are extremely useful, and others not so much. Here, VideoAmy shares a list of 10 of her favorite lesson planning tools available, as well as a playlist of videos to help teachers utilize them.
