I've made these as a game to practice some of the most used comparatives (cheaper, more difficult, larger, more expensive etc.). You may play however you like. I usually use them along with a Ladders and Snakes board (everytime a student stops at a ladder or snake square, they must answer one of these questions. If they're at a ladder square and the answer is correct, they may go up. If wrong, they stay where they are. However, if they're at a snake square and the answer is correct, they stay where they are, but if it's wrong, they have to go down). Have fun!
