Who wrote it?

In this activity each of our level 5 students had to write down twelve sentences about his/her daily routine, after doing so they had to put them all together and mix them up on a box which was in the middle of the classroom. Then they gathered around the box and each one grabbed a sentence, after looking at it they started asking their classmates if he/she wrote that sentence. They learnt how to make fluent questions and had tons of fun.
