I have been researching and experimenting with ways to utilize my teacher chromebook with my interactive whiteboard and this seems to be an option that works really well for me. Install Google Cast for Education on your teacher workstation that is connected to your whiteboard. https://chrome.google.com/webstore/detail/google-cast-for-education/bnmgbcehmiinmmlmepibeeflglhbhlea?hl=en-US Make sure that when you go to use cast that you login to chrome on your desktop (click the little silhouette icon in the upper right hand corner of the browser window). This will allow all of your chrome extensions to load on your desktop. Now just launch google cast for education and setup the cast window. Cast video tutorial (https://www.youtube.com/watch?v=nzTD4l_G5nc) To cast your chromebook screen to the desktop. Open chrome on your chromebook and click the 3 dots next to your chrome extensions bar and scroll down to cast. Select the device (whatever you named the desktop) and select what you want to cast (desktop---your entire chromebook screen or tab---just the tab you are in).
