The object of the game is to make sets of 10. The teacher deals each student 4 cards. Student A picks a card from their hand and figures out how many more they would need to make 10. That is the number that they would asks a classmate for. So if my ten frame has 6 umbrellas on it, I would need 4 more to make 10. Therefore I would ask a classmate for a 4. If they have it they would hand it over and I would read the addition sentence 6+4=10. If not they would tell me to go fish and I will draw a card from the deck.
