I have used this activity in English with many of my classes as an introductory activity at the beginning of the year. Basically the students each say two things about themselves that are true, and one that is a lie, and the rest of the class has to guess which one is the lie.
I never thought of using it as a TPRS activity until I read about it on Martina Bex’s blog. Martina’s adaptation of this activity involves having students write two things that actually happened in the story and one thing that didn’t. Then students find a partner and share their three ‘facts’. The partner has to figure out which thing didn’t actually happen in the story. The partners then switch roles and the other partner shares their three ‘facts’. Then both students have to find new partners and do it all over again.
