This site allows you to customize your own map. You can even create a link so others can access the map you have created. You can add physical systems like water, land, and climate. You can also add populations, culture, political, economic, environment, and society information. You can also draw on the map and place markers. This would be very useful for 7th grade World History and Geography. It could actually have a place in any grade. I have not used it yet, but I plan to. I like everything about it so far.

This website offers educational rap songs and rap videos. You can start a free trial that lasts 30 days, but there is a fee for individuals and better pricing for schools/districts. They have subjects appropriate for K-12. Categories include Vocabulary, Math, Science, Social Studies, Language Arts, and the Week in Rap. There are resources that go along with each rap, like worksheets, assessments, projects, and games. I have used this in the classroom and the kids like to follow along (and even sing) with the printable lyrics. It is a good way to introduce a lesson or to review. The thing I do not like is that you have to subscribe and it costs money, but they do add new material frequently.
