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 that is designed to reveal their current understanding and difficulties. You then review their responses and create questions for students to consider in order to improve their work.
After a whole-class introduction, students work in small groups on a collaborative task matching measurements expressed in decimal and scientific notation. They then match these measurements to everyday objects.
Students then make comparisons between the objects by investigating the size of one object in relation to another. To end the lesson there is a whole-class discussion.
In a follow-up lesson, students work alone again on a similar task to the introductory task.
