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.
The lesson begins with a whole-class introduction in which students review important terms.
Students work in pairs on a collaborative task in which they create data to satisfy written descriptions. When they have constructed their data sets, they separate their data from the descriptive text and pass the data to students in another group, who have not worked with the data to construct a description of their own. The two descriptions are then compared.
In a whole-class discussion students discuss their approaches to the task and what they have learned.
In a follow-up lesson, students receive your comments on the assessment task and use these to attempt another task, approaching it with insights that they have gained from the lesson.
To help students to make meaningful comparisons between sets of data.
Students will develop their abilities in selecting appropriate measures of center and variability in order to summarize the important features of a set of data.
Students will develop their abilities in using quantitative measures to justify an argument.
