Using the search engine OER Commons, I found a comprehensive repository of Spanish I materials that cover Ser and Estar. By browsing the content of this course, I will be able to locate a variety of resources to address my students' specific needs.

Another open educational resource that I found is a PowerPoint Presentation by Ariel Myers, titled Ser y Estar. I located this interactive presentation using MERLOT (Multimedia Educational Resource for Learning and Online Teaching). I added the licensing information to the first slide.
The following TeacherTube video provides a thorough explanation of the different uses of Ser and Estar. It was uploaded by Shannon Probe.
Finally, this last YouTube video is a fun, rigorous review of the content topic chosen for this quest. It was uploaded by SlusionProductions.
