I didn't realize I used a lot of these tools a couple of times a day. The one tool I use everyday is Flipboard on my phone. What I like about Flipboard is you can set up exactly what you want to see everyday, and not have to worry about skipping pages of info you have no interest in. I actually learned about Khan Academy yesterday when a couple of students were playing on the website and enjoyed it. I do not think they realized they were doing math. They had a great time using and playing on the site.
