Thanks Anne for this one too!
Put some objects on a table, for all the class to see.
Go through each item in Indonesian, then ask a pupil to remember all the items on the table, get that pupil to then leave the room.
Take an item off the table and then get that child to come back into the room and tell the rest of the class what item is missing in that language.
If it is correct they get to choose what item to take away next time.
