Teaching Tools

I often teach remotely. I use Skype and an application for a White Board. I love Bing Academic tools for a variety of reasons. Are there more teaching tools on Windows 10 or through Bing that I am missing out? I work with teens and it is helpful for me to have links or tools to share with the student through the Skype Chatbox so that they can apply what I am teaching them and have a source to go back to when I am not around to guide them through a problem.
