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 solutions and create questions for students to consider to help them improve their work.
After a whole-class introduction, students work first individually, then in small groups on a collaborative task, sketching quadrilaterals from a set of properties and identifying the minimal information required to complete the sketch.
A whole-class discussion is held to explore the different combinations of property cards used by students when sketching the quadrilaterals.
Finally students work individually either on a new assessment task, or return to the original task and try to improve their responses.
