This is a useful little extension you can add to Chrome that makes it really easy to share websites with your pupils.
In fact, if they're using Chrome at the time, you can 'push' the page to them and it will just open on their computers without them having to click anything.
If you don't want quite such instant sharing, you can also use it to post the website directly into your Classroom. It's very quick and easy and, if you're searching for resources and you find a good one, you can share it without having to copy the url, go to Classroom, create an announcement etc. I know that's only a few clicks anyway but, if you had a few things to share, it would save you a bit of time.
Click here to go to the Chrome Webstore to install it.
