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.
At the start of the lesson, students respond individually to the questions set.
In groups, students combine their thinking and work together to produce a collaborative solution in the form of a poster.
In the same small groups, students evaluate and comment on some sample responses. They evaluate these responses and compare them with their own work.
In a whole-class discussion, students explain and compare solution strategies.
Finally, students reflect on their work and their learning.
