Teammates write three statements: two true and one false, attempting to trick their teammates. 

One student on each team stands and reads his or her statements to teammates. Without consulting teammates, each student writes down his or her own best guess about which statement is false.

Teammates RoundRobin and defend their “best guess.” (The teacher may or may not ask teams to attempt to reach a concensus.) Teams announce their guess(es).

The standing student reveals which statement was false and congratulates the teammates who guessed correctly. Teammates who were fooled congratulate the standing student.

The next teammate stands to share and the process is repeated
