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

Title	Middle School Portal: Math and Science Pathways (MSP2)
Link	http://msteacher2.org/
Description	The Middle School Portal 2: Math and Science Pathways (MSP2) supports middle grades educators with high-quality, standards-based resources and promotes collaboration and knowledge-sharing among its users. Educators use MSP2 to increase content knowledge in science, mathematics, and appropriate pedagogy for youth ages 10 to 15. MSP2 employs social networking and digital tools to foster dynamic experiences that promote creation, modification, and sharing of resources, facilitate professional development, and support the integration of technology into practice. MSP2 is a project of the Ohio State University College of Education and Human Ecology, National Middle School Association, and Education Development Center, Inc., and is funded by the National Science Foundation. The partners integrate resources, tools, and services across projects, and support multiple methods of resource discovery to meet the needs of this audience.
