"TAXI!!" (Ed Snyder)
1. Students will discover different methods of using probability.
2. Students will explore different ways of tracking and recording probability.
This activity is designed for students to discover the concept of a probability as well as become familiar with the concepts of permutations and combinations.
Introduce to students the concepts of permutation and combinations. Suggest to the class that taxi cab drivers often take several different routes in order to reach the same destination. There are generally many contributing factors as to which route they will take. This activity will allow students to explore and apply probability as well as, explore different techniques in organizing data.
1. Begin by discussing the problem statement.
2. Have students form small groups.
3. Distribute "TAXI!!" activity sheet
4. Have each group select a spokesperson to report their findings to the class.
5. Discuss students results as it relates to election theory.
"TAXI" activity sheet, chalk board, overhead projector and transparencies.
Introduction (5 min.), group work (25 min.), presentations of group work and class discussion (20 min.).
