"This week Kahoot, the wildly popular quiz game platform, released a new team mode. The new team mode is designed to be used with students who are sharing computers, tablets, or phones. In team mode students arrange themselves in teams around a shared computer or tablet. When you start a Kahoot game you'll now choose "team mode." With team mode selected your students will be prompted to enter a team name and a list of the team members.
After the teams have entered their names you will be ready to start the game. One of the nice features of team mode is that students have time to discuss their answer choices before they are allowed to submit a response. From there the game is played and scored as any other Kahoot game is."
This is particularly useful this year before BYOD is whole school as it doesn't require all students to have devices!
