This I Have...Who Have game for collective nouns is great for a review of this concept. There are 24 cards which each features a different collective noun.
To play: pass out all the cards to your students. The student with the first card starts the game. The student with the answer gives the answer from their card and then asks the question on their card. Play continues in this way until your class reaches the last card.
