In case you are trying the MARS MAP Classroom Challenges for the first time, it is recommended that you read the Brief Guide for teachers and administrators before you get started.
This lesson is designed to enable students to develop strategies for solving real-life problems. The problem is characterized by the use of appropriate units and formulas.
Before the lesson, students tackle the problem individually. You assess their responses and formulate questions that will prompt them to review their work.
At the start of the lesson, students respond individually to the questions set, and then work in groups to combine their thinking and produce a collaborative solution in the form of a poster.
In the same small groups, students evaluate and comment on some sample responses. They identify the strengths and mistakes in these responses and compare them with their own work.
In a whole-class discussion, students explain and compare the solution strategies they have seen and used.
Finally, students reflect on their work and their learning.
