I use this game with young children to practise the names of rooms in the house and interrogative sentences with the verb to be. Students work in pairs. Every student gets the worksheet and puts ticks on the 1st field to place every person into a room. Then students in turns ask each other questions: Where's mummy? Is she in the kitchen? - No, she isn't. / Yes, she is. Getting positive or negative answers the students put + or - on the 2nd field. The student who finds all the family members first is the winner.
