This may not be a "classroom teachable" lesson but it sure would be cool for down-time, inside recess, etc. You could maybe even use it for a science lesson? I'm not sure. Google Chrome paired up with Lego to create a "stem online lego lab" of some sorts.
You can learn to build things, explore things that other people have built, or build from scratch whatever you want. This would be really cool for lego-loving kids or our techie kids. You don't have to sign in to build or play, but if you want to save what you have done, you will have to sign in using a google account. https://www.buildwithchrome.com
