Slowly reveal one of the flashcards. Students put up their hands to guess the right sentence, e.g. “It is a reindeer” or “They are Xmas trees”. Anyone who puts up their hand and is chosen to speak loses one point if they are wrong in any way, including wrongly guessing if the card will show singular or plural.
