There is a starting card and end card. There is total 16 cards, so it is good for half of the class or a small class in general. This is a great game for a lesson on multiplying decimal numbers with whole numbers. Pass out the cards to the class and have the person who has starting card to go first. Every one should go once at least. Towards the end, all the card will be used. The person who has the end card should go last. Also, the cards were already in order, so you have the answer key with you as well.
