**Subject Area:**Mathematics

**Grade:**6

**Domain-Subdomain:**Statistics & Probability

**Cluster:**Level 1: Recall

**Cluster:**Develop understanding of statistical variability. (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.

## STEM Lessons - Model Eliciting Activity

After reading the market report for the real estate sales in Miami during the first quarter, students will decide which type of property they want to consider for investment that can be sold during the next year and still make a profit from the sale. In addition, students will determine the best location to make the investment. Luxury homes are selling faster this year, while there is not inventory for single families houses. The median prices for condos and apartments are lower, but the number of sales is going up. Students also consider price fluctuation between different locations.

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