This exploration investigates how many ways there are to travel through an array of streets. The exploration, part of the Figure This! collection of 80 math challenges, examines the relationship between the number of intersections and the number of possible routes. The challenge page contains links to a solution hint, the solution, and other similar investigations. The solution describes and illustrates how a number pattern is embedded in the question. Similar investigations ask the student to analyze other arrays and to find the shortest possible routes. The importance of these routing questions to the transportation industry is noted. Information and a short book list about the patterns found in Pascal's triangle are also included. 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.
