Toward the end of last summer Google added a feature to Classroom that I have not had an opportunity to explore until now: Google Topics. When you are creating a post or assignment in Google Classroom you can give it a topic. Then every post that falls under that same topic gets tagged with that topic. Google then creates a "Table of Contents" that remains on the left side of your Classroom Stream page. Really cool feature, Google!
To draw a note just open the app and tap the pen icon to start drawing. You can also add a drawing to a text, image, or voice note. To add drawings to an existing note tap the three dots in the upper-right corner of the screen and select "add drawing."
For some students one of the obstacles to understanding how to solve a mathematics problem is understanding the vocabulary used in the problem. Once they understand the meaning of terms they have an easier time understanding and solving the problems. Having a glossary of terms often helps students get to the heart of a mathematics problem.
If you are a math teacher, this would be a great link to add to your website!
All points on the Histography timeline are based on Wikipedia entries, but don't let that discourage you from using it. I think viewing and manipulating the Histography timeline could be a good way for students to discover events and topics that they otherwise might not find in a typical history textbook. That process of exploring the timeline could lead students to further investigate an event or topic outside of the Wikipedia entry.
If I were teaching history I would definitely use these videos in class to share how news was passed around in older times when the common people didn't read.
