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.
Before the lesson, students work individually on an assessment task designed to reveal their current understanding. You then review their responses and create questions for students to consider when improving their work.
Students work in small groups on a collaborative discussion task, placing decimal/percent, and fraction cards in order, along with area and linear diagrams that assist them in justifying and explaining their thinking.
In a whole-class discussion, students discuss what they have learned.
Finally, students revisit their initial work on the assessment task and work alone on a similar task to the introductory task.
