Resource Title:What's round, hard, and sold for 3 million dollars?
Description:This activity challenges students to determine which is worth more today, Babe Ruth's 1927 home-run record-breaking ball or Mark McGwire's 70th home-run record-breaking ball that sold in 1999 for 3 million dollars. The activity is part of the Figure This! collection of 80 online mathematical challenges emphasizing real-world uses of mathematics. To solve this challenge, students build a table and observe the growth pattern as the value of Ruth's ball doubles every seven years. The activity's web page contains links to a solution hint, the solution, other math questions about interest rates, and print resources featuring books and web links about baseball. Students are encouraged to talk to family members about savings accounts and the costs for buying a car or borrowing money for school. Copyright 2005 Eisenhower National Clearinghouse
