Question: Maddy's 4th grade class needs to make 1000 Valentine's Day cards to get a pizza party. There are 30 kids in the class. If everyone makes 8, how many more cards will they need to make to get a pizza party? Think carefully first, then make a decision:
If 30 kids each make 8 cards, they will have made 240 cards because 30 * 8 = 240. Since 1000 - 240 = 760, they need to make 760 more cards. So the answer is 760.
