I‘ve posted before about how much I (and my students) like the BBC games Gut Instinct and Mia Cadaver’s Tombstone Timeout. Those games test student knowledge of English, Math, and Science at various levels and, more importantly, allow you to create private virtual “rooms” so that the whole class can compete against one another.
Well, I just discovered the the BBC has another similar game called Elemental that has a a bit higher level English, Math and Science questions than the other two games. In Elemental, you can also easily create private rooms, but it appears that you might have a maximum of four players in each room (but I’m not sure about that).
I’m placing the link on my website under Word and Video Games.
