CosmoBuzz

This resource couldn’t be any easier to use. It’s an online multiplayer buzzer system you can use with your students for drill or assess them while you teach. Have students answer questions in a text box or drill them for speed in recalling facts. Students love competition! You can also just have them use the buzzer to ring in and be ready to answer when called upon. It’s free and very simple to use.
