Be creative, build a city!
Indulge your inner creator and build cities in one of three scenarios. If you want to save your cities and come back later, you'll need an account, but students can play with no account and simply screenshot their creation. (Returning to the same computer later will allow you to continue building since cookies from the site will keep track of changes.)
Young kids can have fun practicing mouse skills, and the resulting cities can be used as a story prompt, or illustration for an existing adventure, or even language practice for ELL or other language classes. ("Je vois deux maisons, un camion et trois voitures.") It's not mobile friendly!
