My AP teacher utilized this website before as there are multiple-choice quizzes to test students for enrichment. Maybe, in the future, this can be utilized on some of the unit tests and other assessments.

This is the website for the Metropolitan Museum, the largest art museum in the U.S., if not the world. It is located in New York, but online you can find whatever art pieces available.

This is a website full of blank maps. If you guys want to do a labeling quiz or a coloring worksheets, students might learn a lot from these geography stuff.

I utilize this website for primary sources: it has many speeches, debates, interviews, especially in audio, text, and videos of many sorts of mediums.

This site is very useful if you want to utilize primary sources that is valuable for Social Studies Educators: Oral Historiography.
