Student A and student B are two siblings who " have lost their memory" as a result of a serious fight. They ask each other general/special questions to find out the facts they don't remember and circle the right words / fill in the missing information. If they don't know how to write a word, they can ask the partner to spell it.
e.g.: A - Is our grandma's name Liz? A - What's my name?
B - No, it isn't. Her name is Mary. B - Your name's Lucy.
A - Is our grandad on holiday? B - How old am I?
B - Yes, he is. A - You're 11.
