- Reporting the number of observations.
- Describing the nature of the attribute under investigation, including how it was measured and its units of measurement.
- Giving quantitative measures of center (median and/or mean) and variability (interquartile range and/or mean absolute deviation), as well as describing any overall pattern and any striking deviations from the overall pattern with reference to the context in which the data were gathered.
- Relating the choice of measures of center and variability to the shape of the data distribution and the context in which the data were gathered.

**Subject Area:**Mathematics

**Grade:**6

**Domain-Subdomain:**Statistics & Probability

**Cluster:**Level 3: Strategic Thinking & Complex Reasoning

**Cluster:**Summarize and describe distributions. (Additional Cluster) -

Clusters should not be sorted from Major to Supporting and then taught in that order. To do so would strip the coherence of the mathematical ideas and miss the opportunity to enhance the major work of the grade with the supporting clusters.

**Date Adopted or Revised:**02/14

**Date of Last Rating:**02/14

**Status:**State Board Approved

**Assessed:**Yes

**Assessment Limits :**

Displays should include only dot/line plots, box plots, or histograms.**Calculator :**No

**Context :**Required

## STEM Lessons - Model Eliciting Activity

Students are asked to break down player statistics into percentages to determine the best players to send to an all star team. Students are then requested to write about the procedure used to make their decisions. Students are then asked to rank the players from one to five with one being the top pick.

Model Eliciting Activities, MEAs, are open-ended, interdisciplinary problem-solving activities that are meant to reveal students’ thinking about the concepts embedded in realistic situations. Click here to learn more about MEAs and how they can transform your classroom.

In this MEA, students will apply the concepts of heat transfer, especially convection. Students will analyze factors such as temperature that affect the behavior of fluids as they form convection currents.
