Students must work together in cooperative groups in order to successfully complete this problem. This lesson appears as part of a Mathematical Problem Solving Resource that will be included on the Cadre CD made available at all Cadre workshops. This resource is a year long approach to teaching problem solving and thinking skills to students in the intermediate grades. All materials on the CD are written in both Macintosh and Windows readable formats. This problem requires student to use time measurement skills, computation and critical thinking skills.
Students work in small groups to actively create a solution to the problem.
By actively, it is meant that students must be able to act out their solution to the problem. It is important that all groups share their solution methods with the rest of the group in order to generate questions and discussion relevant to the problem. After completion of write-up students will work in pairs and share their papers with their partner. Partners will score each other's papers based on the Student Scoring Guide . After scoring papers students will share the scores they gave their peers and discuss why they gave the scores they did.
